2005/02/24 23:28:02-08:00 hp.com!davidm Fix merge-conflict. 2004/11/16 14:09:01-08:00 hp.com!davidm Manual merge. 2004/11/05 00:14:10-08:00 hp.com!davidm Fix merge conflict. 2004/11/03 13:57:00-08:00 hp.com!davidm Merge. 2004/10/19 23:06:23-07:00 mostang.com!davidm (pkg_minor): Switch to 99. (pkg_extra): Switch to -alpha. (CFLAGS): Add -fexceptions if we're compiling with GCC. It's needed to get the proper unwind tables on platforms with DWARF unwind info (well, at least on x86 it's needed). (Logical change 1.290)
