SunOS 5.8 Reading specs from /usr/local/lib/gcc-lib/sparc-sun-solaris2.8/2.95.3/specs gcc version 2.95.3 20010315 (release) In the posix related libaries there are two forign call definition.

foreign import ccall unsafe "getpwuid_r" c_getpwuid_r :: CUid -> Ptr CPasswd -> CString -> CSize -> Ptr (Ptr CPasswd) -> IO CInt

foreign import ccall unsafe "getpwnam_r" c_getpwnam_r :: CString -> Ptr CPasswd -> CString -> CSize -> Ptr (Ptr CPasswd) -> IO CInt

But the gcc says there are too many argument. There are two ways to go around. I change the foriegn call definition "getpwuid_r" ==> "__posix_getpwuid_r" I change the foriegn call definition "getpwnam_r" ==> "__posix_getpwnam_r"

Thanks, I'll look into this. Cheers, Simon
