Subject compilation fails in mingw
Date Wed, 19 Aug 2009 19:28:09 GMT
Because mingw's version of GCC only "likes" paths with '/' 's building
of buildr "from source" in windows with mingw fails (well, in reality
rjb fails).

c:/ruby/bin/ruby.exe extconf.rb
checking for jni.h... *** extconf.rb failed ***
Could not create Makefile due to some reason, probably lack of
necessary libraries and/or headers.  Check the mkmf.log file for more
details.  You may need configuration options.

Gem files will remain installed in
c:/ruby/lib/ruby/gems/1.9.1/gems/rjb-1.1.6 for inspection.
Results logged to c:/ruby/lib/ruby/gems/1.9.1/gems/rjb-1.1.6/ext/gem_make.out

possible fixes:
I could commit a patch for extconf.rb
the distributor could use the rake compiler
to generate binaries for the several platforms [this one is 1.9.1 on
