<DIV>Apparently you’ve updated your GCC more recently than I have, and now in
4.8.3 this old-autotools method of checking for the existence of a function is
an error, where it used to be a warning. I’m really surprised the grouping of a
warning would be changed in a point release like that... the right solution is
to update our autotools version, but that’s a big job that we haven’t put enough
full-time work into yet. I’ll try to think if there’s a quick short-term fix for
this, but in the meantime can you try reverting your GCC version to the previous
release through Cygwin’s setup program?</DIV>
