Bruce Korb <autogen@linuxbox.com>
* fixinc/inclhack.def
(AAB_svr4_replace_byteorder): added. Takes advantage of GCC features
(unixware7_byteorder_fix): added. Removes conflicts for new defs
in net/inet.h.
(svr5_mach_defines): added. Like svr4_mach_defines, with new syntax
(svr4_endian): enabled with SVR5
(svr4_mkdev): simplified syntax and enabled with SVR5
Sun Nov 14 18:49:37 1999 David O'Brien <obrien@FreeBSD.org>
* configure.in: Handle libgcc2 threads support on FreeBSD platforms.

This isn\'t actually used by GCC. It is installed by fixinc.svr4.
For big-endian machines these functions are essentially no-ops.
For little-endian machines, we define the functions using specialized
