--no-ansi (mgnuc) and --no-ansi-c (mmc) have not actually done anything for
many years now. Deprecate these options and remove their "use" throughout most
of the Mercury system. (The remaining uses are in the Makefiles for the Boehm
GC, which need to be updated separately.)
Also deprecate the internal compiler option --cflags-for-ansi.
compiler/options.m:
Document that --no-ansi-c is now deprecated.
Document that the internal option --cflags-for-ansi is now
deprecated.
compiler/compile_target_code.m:
Do not pass the ANSI options to the C compiler.
scripts/mgnuc.in:
scripts/mgnuc_file_opts.sh-subr:
Deprecate the --no-ansi option; delete code that no longer does
anything useful.
configure.ac:
Delete the configuration variable CFLAGS_FOR_ANSI; it is only ever
set to be empty. (The comment talks about --no-ansi doing other things
in the mgnuc script. It used to also cause some preprocessor macros
to be defined for compatibility with the system headers on some
platforms -- that has not been the case since 2013.)

Announce the above.
The recent change to sparse_bitsets broke the lex library in extras.
Specifically, we now now need to make characters an instance of the
uenum typeclass. This diff does so.
library/char.m:
Add predicates and functions for converting between unsigned integers
and characters.
Make characters an instance of the uenum typeclass.

library/ops.m:
Fix wording, and a dangling reference.
samples/calculator2.m:
Update to use the new ops.m.
Mercury inherited its original system of operator priorities from Prolog,
because during its initial development, we wanted to be able execute
the Mercury compiler using NU-Prolog and later SICStus Prolog.
That consideration has long been obsolete, and now we may fix the
design error that gifted Prolog with its counter-intuitive system
of operator priorities, in which higher *numerical* operator priorities
mean lower *actual* priorities. This diff does that.
library/ops.m:
Change the meaning of operator priorities, to make higher numerical
priorities mean also higher actual priorities.
This semantic change requires corresponding changes in any other module
that uses ops.m. To force this change to occur, change the type
representing priorities from being a synonym for a bare int to being
a notag wrapper around an uint.
The old "assoc" type had a misleading name, since it is related to
associativity but is not itself a representation of associativity.
Its two function symbols, which used to be just "x" and "y", meant that
the priority of an argument must be (respectively) greater than,
or greater than equal to, the priority of the operator. So rename
x to arg_gt, y to arg_ge, and assoc to arg_prio_gt_or_ge.
Rename the old adjust_priority_for_assoc predicate to min_priority_for_arg,
which better expresses its semantics. Turn it into a function, since
some of its users want it that way, and move its declaration to the
public part of the interface.
Add a method named tightest_op_priority to replace the use of 0
as a priority.
Rename the max_priority method as the loosest_op_priority method.
Add a method named universal_priority to replace the use of
max_priority + 1 as a priority.
Add a function to return the priority of the comma operator,
to allow other modules to stop hardcoding it.
Add operations for comparing priorities and for incrementing/decrementing
priorities.
Change the prefix on the names of the predicates that take op_infos
as inputs from "mercury_op_table_" to "op_infos_", since the old prefix
was misleading.
Add a note on an significant old problem with an exported type synonym.
library/mercury_term_parser.m:

Use predmode declarations when possible.
Flatten camelCase.
Add prefixes to the names of function symbols and fields
if this avoid ambiguity, either with other parts of this code,
or with standard Mercury function symbols or predicates.
Replace uses of graphic characters such as ',' and '-' as
general purpose function symbols with normal, alphanumeric
function symbols. (Uses of graphic characters to stand for themselves
in xml.parse.chars.m are unaffected.)
Replace uses of graphic symbols such as ',' '->' and '[|]' as type names.
Improve some other names as well.
Convert (C->T;E) to (if C then T else E).
Replace tabs with spaces.
Delete unused imports.
Make the order of definitions match the order of declarations.
extras/xml/tryit.m:
Put the code for handling a single command line argument into its own
predicate.
Replace see/seen with read_named_file_as_string.
Avoid using !IO to pass around the parser state.
Instead of writing out the parse tree as a single very long line,
convert both the DTD and the HTML code to a prettyprinter doc,
and print that. This makes the output actually readable, and
also makes it usefully diffable as well.
extras/xml/Mmakefile:
Replace the old do-nothing check action with one that actually does
check whether the code in this directory can do at least one simple task,
the one mentioned in in samples/README. It would be nice of we had
more tests, more extensive tests, or (preferably) both, but that would
require someone who knows the code significantly better than I do.
Add a rule for making the tags file.
Compile the modules in this directory with the same default mmc flags
as we use in the compiler directory.

use of these.

Delete a reference to promise_only_solution in a comment.
tests/declarative_debugger/trust.exp:
tests/declarative_debugger/trust.inp:
tests/declarative_debugger/trust_1.m:

the user-defined comparison on the type exported by that module.

Trail segments have been the default in trailing grades since Mercury 20.06.

they no longer do anything.
