wx 2.6 cvs branch: configure --prefix problem w/ gcc in cygwin

[John Labenski]

Well, I dunno what happened to cygwin, but I'm guessing it's a problem
with an update from them.

If I run either the script or the same on the command line, but DO NOT
pipe the output to a file like this "... > config_gcc_static_out" I do
not have the problem below. This is too bad since I like to save the
output so I can refer to it if I have to.

It seems very strange indeed, but very reproducible.

Thanks,
    John Labenski
