This module is meant to be used at Makefile.PL time ( so I think it belongs to ExtUtils ); it makes easy to override values in %Config; basically you create a module like this: package Foo; use ExtUtils::FakeConfig cc => 'my_cc', cflags => 'funny flags'; 1; and do perl -MFoo Makefile.PL I use it to compile ActivePerl modules with MinGW, but it has many other uses, especially if you want to compile modules with a different cc your Perl was compiled with. I don't plan to put it in CPAN ( yet ), just want comments about the name. Regards Mattia
