Here's the patch... fairly straightforward, if I've understood the SUS
spec for the function correctly :-/

As for the apparent hangs in bash/ls/etc. - well, perhaps it was my
patch, perhaps not, as I was building from latest cvs source.  Since
I can't find any documentation that indicates if a particular method
for adding an export to cygiwn.din needs to be followed, this patch
simply tacks sem_getvalue to the end of the list.
