1st question:  if you are trying to build from the standard source, rather
than the one from the cygwin mirror directories, why?

2nd question:  are you sure that the target selected automatically was not
i686-pc-cygwin32? It may be better to specify the target so that it is
identical to the host.  If your --host and --target do not match exactly,
you are doing a cross build, which requires a copy of the include files to
be present in the appropriate target build directory.

3rd question:  (depending on your answer to #2) did you remember to copy
/usr/include to /usr/local/i686-gcc/i686-pc-cygwin32/include (if that
corresponds to the selected target) before running configure?  That should
postpone problems finding <windows.h> until the libf2c build, where you
really should be using the cygwin copy of the sources, even if you choose
the standard gcc-2.95.2 or 2.95.3 .  The keepers of gcc-2.95.3 have declined
the suggestion that libf2c should correspond with any version of cygwin
other than -b20.
