Subject: types.h: Use __builtin_bswap* with clang.
X-Git-Tag: 2.02-beta3~372
X-Git-Url: http://git.ipfire.org/cgi-bin/gitweb.cgi?a=commitdiff_plain;h=77697d14e55eaf878639a630ab45563fa9556a97;p=thirdparty%2Fgrub.git

types.h: Use __builtin_bswap* with clang.

clang pretends to be GCC 4.2 but we use __builtin_bswap* only with GCC 4.3+.
clang support __builtin_bswap*, so use it.
