Since many files now use non-ANSI constructs ('long long',
	substructure initializers, implicit signedness conversions, ...)
	you shouldn't use "gcc -ansi -pedantic". On our ix86-linux-gnu
	system this change reduces the number of gcc-3.4.3 warnings from
	originally 3034 to 1460!
	(Still by far to many, as compared to 42 for XFree86-4.5.0.)

	I have reported the change in "xfree86.cf" to XFree86 about a year
	ago.
