byteswap.h: fix gcc ver test for __builtin_bswap{32,64}

2012-12-03T19:54:31+00:00

The __builtin_bswap* functions were introduced in gcc-4.3, not gcc-4.2.
Fix the __GNUC_PREREQ tests to reflect this.

Otherwise trying to compile code with gcc-4.2 falls down:
In file included from /usr/include/endian.h:60,
                 from /usr/include/ctype.h:40,
/usr/include/bits/byteswap.h: In function 'unsigned int __bswap_32(unsigned int)':
/usr/include/bits/byteswap.h:46: error: '__builtin_bswap32' was not declared in this scope
/usr/include/bits/byteswap.h: In function 'long long unsigned int __bswap_64(long long unsigned int)':
/usr/include/bits/byteswap.h:110: error: '__builtin_bswap64' was not declared in this scope

Fix __bswap_64 return type in generic bits/byteswap.h.

Avoid -Wconversion warning for htons

2012-06-21T13:49:33+00:00

Use __builtin_bswap32/64 in __bswap_32/64 for GCC >= 4.2

2012-04-06T23:13:40+00:00

Add byteswap-16.h for __bswap_16
