Hi,

I am trying to build ruby-xslt on Windows XP. The first step is to run

```
ruby extconf.rb

```

which fails. mkmf.log contains the following which can’t work on my  
system since there is no cl in my path; I assume that’s because I don’t  
have MS Visual Studio. I had installed MinGW and MSYS hoping that that  
would allow me to build ruby-xslt with gcc and friends. Is there a way  
to get mkmf to use gcc instead of cl when running its config tests?

Thanks,  
Terry
