*BSD folks please test.

I built the 20080529 snapshot with this patch and my light testing of ghci showed no problems (FreeBSD 7.0/x86_64).

20080531 and NetBSD-amd64 4.0, not so good:

GHCi, version 6.8.2.20080531: http://www.haskell.org/ghc/ :? for help Loading package base ... linking ... done. Bad system call (core dumped)

SIGSYS appears to happen in select(), is all I could get out of gdb. Prior to the patch, it was the usual error.

I guess the error in the linker was masking the SIGSYS in select(), because it occurred first. So now we need to figure out what is causing this SIGSYS.

Otherwise, 20080531 seems to work as well as 6.8.2 release on NetBSD-amd64. NetBSD defines ELF64_ST_TYPE and ELF64_ST_BIND.

Unfortunately, it won't build with the GNU "ar" that's standard on this platform. It can't index archives as big as libHSbase.a: apparently, it allocates too many moderately large hash tables for the many small modules in that archive, and runs out of memory. I worked around this by reducing the default hash table size in libbfd.so. I'm not saying any of this makes sense, it's just what I eventually managed to get working. Otherwise, it builds smoothly.

Perhaps turning off -split-objs would also work around this problem? Cheers, Simon
