I can't install or build Perl modules with cpan or cpanp because it 
passes -fstack-protector argument flag to gcc and that argument is not 
accepted in the cygwin version of gcc.

Here is the error message from cpan while trying to install a Perl module.

gcc -c  -I/usr/include/openssl -DPERL_USE_SAFE_PUTENV -U__STRICT_ANSI__ -fno-strict-aliasing 
 -pipe -fstack-protector -I/usr/local/include -DUSEIMPORTLIB -O3   -DVERSION=\"0.57\" 
 -DXS_VERSION=\"0.57\"  "-I/usr/lib/perl5/5.10/i686-cygwin/CORE"   SSLeay.c
cc1: error: unrecognized command line option "-fstack-protector"
make: *** [SSLeay.o] Error 1

Here is the cc line when running perl -V. It has the -fstack-protector flag. 
How did this perl get built with that flag when that version of gcc is not 
in Cygwin distribution?

    cc='gcc', ccflags 
='-DPERL_USE_SAFE_PUTENV -U__STRICT_ANSI__ -fno-strict-aliasing -pipe -fstack-protector 
 -I/usr/local/include',    optimize='-O3',


The cygwin setup (version 2.673) has gcc 3.4.4-999 only, which is what I 
have installed. The latest version of gcc is 4.4.2.

I might be able to add a cc flag in cpan, but I don't know how to take one 
out. I was able to use cpanp, go into the build directory, edit the 
Makefile, delete the argument, and built the module, but when a module has 
dependencies, this is a nightmare to do.
