Estimated hours taken: 0.75 Report an error if the first argument of a `some' goal is not a list of variables. compiler/prog_io.m: compiler/prog_io_util.m: Move `parse_list_of_vars' from prog_io.m to prog_io_util.m. compiler/prog_io_goal.m: Check to make sure that the first argument to a some goal is a list of variables. (If not, we don't report an error here -- the error will be reported by typecheck.m.) compiler/typecheck.m: Report an proper error message if there is a call to an undefined predicate `some/2'. Also add `some/2' and `all/2' to the list of language builtins for which we report a special error message if they occur as undefined function symbols. tests/invalid/Mmakefile: tests/invalid/some.m: tests/invalid/some.err_exp: Regression test for the above change.
Reportedly Mercury does not work on Solaris 2.5.1 if it is compiled with
gcc 2.7.x. It should however work fine on Solaris 2.5.1 if you compile
it with gcc 2.8, or if you use gcc 2.7.x with an earlier version of Solaris.
The binary distribution for Solaris that we distribute was compiled
with gcc 2.7.2, so if you have Solaris 2.5.1, you may need to compile
Mercury yourself from our source distribution.
("Solaris 2.x" is also known as "SunOS 5.x".)
