compiler/mercury_compile_args.m:
Instead of writing out any error messages (and setting the exit status)
in different ways in different circumstances, return all error messages
to our caller, as error_specs, and the option_table needed to print
those error_specs out.
Simplify the code that actually does the expansion of @file arguments,
both by invoking higher level primitives than were available when
the original code was written, and by avoiding repeatedly putting
arguments info ok/1 wrappers and taking them out again.
Change the argument list of setup_all_args to delete the ErrorStream
argument and pass only ProgressStream, because its only caller always
passes the *same* stream as both arguments.
compiler/mercury_compile_main.m:
Print the error messages that mercury_compile_args.m now returns.
Standardize on printing "mmc:" before those messages to identify
the program reporting those errors. (The old code could print any
one of "mercury_compile:", "mmc:", the name of the executable,
or nothing.)
compiler/file_util.m:
Add two utility functions for the new code in mercury_compile_args.m.
compiler/handle_options.m:
Add an XXX.
