[m-dev.] diff: don't pass -Wtraditional to gcc

[Fergus Henderson]

Estimated hours taken: 0.25

scripts/mgnuc.in:
compiler/mercury_compile.m:
	Don't pass `-Wtraditional' to GNU C, since this results in
	many warnings with gcc 2.96, e.g. about the use of ANSI C
	preprocessor constructors such as string concatenation and
	indented `#define'.  We don't care about compatibility with
	pre-ANSI C compilers.
