Summary: SunOS5.8: getEffectiveUserNamem, crash illegal instruction

Initial Comment:
hello.  
  
on SunOS 5.8, with a fresh compiled ghc (configure  
 -prefix=/home/xxx/local && make)  
 and the some for the precompiled version. 
  
the simple programm crash (see test.hs).  
gdb says > gdb ./test 
This GDB was configured as "sparc-sun-solaris2.8"... 
(gdb) run 
Starting program: /home/xxx/test 
Program received signal SIGILL, Illegal instruction. 
0x1f16dc in getgrnam_r () 
(gdb) 
 
-- test.hs 
import Posix 
 
main :: IO () 
main = do 
        user <- Posix.getEffectiveUserName 
        print user 
---- 
thx in advance

A fix for Solaris has been committed for this, defining
_POSIX_PTHREAD_SEMANTICS to get the proper getgrnam_r. 
It is untested as yet.

See this thread:        
http://www.haskell.org/pipermail/glasgow-haskell-bugs/2003-September/003601.html

At the time it was also noted that getgrnam_r functions did
not work on FreeBSD and OpenBSD as well, although for
different reasons. This hasn't been resolved yet.
