Hi Gary,

According to Gary V. Vaughan on 8/5/2006 9:03 AM:

That's quite a list of platforms.

Can you include the relevant portions of config.log, where it was
determining whether wchar_t and wcwidth were supported?

That would also be a gnulib issue, since it is in the lib directory.  But
nothing jumps out at me as an obvious source of the failure.

OK, so AIX 4 didn't provide any of the usual preprocessor macros such as
__unix__.  What DOES it provide, that we can key off of in src/m4.h to
determine whether we should treat it as a UNIX-y system?

Also, any feedback on this question?
