Have you tried running gcc from the command line? Have a look at the
thread started at http://cygwin.com/ml/cygwin/2010-01/msg01228.html
maybe your case is related. What does
cygcheck `which gcc`
reveal, if anything? It should be something like
$ cygcheck `which gcc`
 -> C:\cygwin\etc\alternatives\gcc
 -> C:\cygwin\bin\gcc-4.exe
C:\cygwin\bin\gcc-4.exe
  C:\cygwin\bin\cyggcc_s-1.dll
(and more dlls)
I think.

I'm surprised about the error in the compilerok.log, -fstack-protector
was introduced as a patch sometime during the lifetime of gcc 3 (whether
it was ever introduced into the official Cygwin package I don't know,
however) and then in the main build in gcc 4. Maybe you have an old
version of gcc/cc1?
