I was not offended.  I am habitually exasperated by people who offer bug
reports with no details but with wild theories about the causes of their
problems gleaned from misreading of email archives.

Checking for ANSI C header files does not scream out "Symlink problem!"
to me.

But, if you think about it, if Cygwin was actually trying to execute a
symlink directly rather than the program it referred to then it would be
broken.

If you are referring to trying to run a symlink from, say, the command
line, or the Start->run menu then, that could be a problem.  Symlinks
are a cygwin construction and Windows doesn't know anything about them.

When you are running a configure script you are in a cygwin environmennt.
Cygwin would be a very poor UNIX emulation environment if you were unable
to run a symlink linked to a program.

I think someone else hit the nail on the head.  The cross configure
script may be building non-Windows applications and trying to run them.
On UNIX that would cause a nice clean failure.  On Windows, it will
cause other strange and random results.
