Mingw compilation: Here's how

I tried to build ruby-1.6.7 with Mingw-2.0.0-3 and
MSYS-1.0.8-2002.09.07-1 on a “windows me” system. I had to make these
changes to the ruby source code:

When configuring, use a prefix argument with a drive letter, and use
forward slashes as path delimiters, like this:

./configure --prefix=c:/PROGRA~1/Ruby

after that, run “make”, “make test” and “make install”. "make install"
will pause for some 30 seconds right at the beginning, don’t interrupt,
it will continue!

I also checked that this patch does not harm the cygwin, msvc6, or linux
builds.

I guess I’ve fixed. Try the latest CVS(ruby_1_6 branch) or
stable-snapshot.

Thanks for the hint. This does indeed fix the Mingw compilation.

Strange: If I configure with --enable-shared, then Mingw actually
tries to compile the curses extension (and fails because of the
missing curses header file). This does not happen if I compile without
the --enable-shared command line argument.
