This implies the system does not have SSE (SSE 1), but in fact what you're concerned about is SSE 4. This will be confusing for users of older x86-64 processors, where SSE and SSE 2 are architecturally guaranteed even though SSE 4 is not present. > +else > + BASIC_CFLAGS += -msse4 > +endif You probably also want to autodetect when the system is not x86(-64)? and turn this off. I doubt PowerPC/SPARC/ARM users are going to want to have to disable it manually. -- brian m. carlson / brian with sandals: Houston, Texas, US +1 832 623 2791 | http://www.crustytoothpaste.net/~bmc | My opinion only OpenPGP: RSA v4 4096b: 88AC E9B2 9196 305B A994 7552 F1BA 225C 0223 B187
