It's odd that regex worked, but quotearg and mbswidth did not.  Let's
look at quotearg first.  quotearg.c includes wctype.h, and wctype.h
should declare _ctmp_.  But I see now that it declares it to be
'static', whereas the system .h file declares it to be 'extern'.
Perhaps that's the problem?  (C99 says the behavior is undefined in
this case.)

Does the following further patch fix things for you?
If not, what does the resulting lib/wctype.h look like?
And what is the output of "cc -E -I. quotearg.c | grep ctmp"?
