That would be helpful, because both of the previous complainants seem
to have wandered off without helping us get to the bottom of it :-(.

What I'd like to see at this point is the portion of config.log where
the configure script is trying to probe for wcstombs_l. For example,
on a machine that has wcstombs and not wcstombs_l, I see:

...

It would also be interesting to check what would happen if configure
actually tried to probe for mbstowcs_l, instead of making assumptions.
To do that, copy the test program above (removing the "| " indentation),
replace "wcstombs_l" by "mbstowcs_l", and then try to compile it ---
but be sure to use the compile command shown in your config.log, not
mine.
