The mmx (and sse, sse2 etc) use flags do not normally have anything to do with the gcc -mmmx etc flags. Normally in a configure for a package they will cause a optimised assembler to be included for certain functions rather than using 'generic' C code for them. In ebuilds the mmx USE flag normally selects these configure options when building the package, so (unlike using CFLAGS=-mmmx) are quite safe in most cases. -- [EMAIL PROTECTED] mailing list
