http://redmine.ruby-lang.org/issues/show/799

Author: Luis Lavena
Status: Open, Priority: Normal
Target version: 1.9.1

Hello everybody.

I tried to cross compile 1.9.1-preview1 under ubuntu. It succeeded with 1.8.6-p287 and p114 but failed with 1.9.

Used the following compile flags:
<pre><code>--host=i586-mingw32msvc --target=i386-mingw32 --build=i686-linux --enable-shared</code></pre>

This is the snipped of the output

<pre><code>make[1]: Leaving directory `/home/luislavena/sources/cross-ruby/builds/ruby-1.9.1-preview1'
make -f enc.mk RUBY="ruby -I/home/luislavena/sources/cross-ruby/builds/ruby-1.9.1-preview1 -rfake " MINIRUBY="ruby -I/home/luislavena/sources/cross-ruby/builds/ruby-1.9.1-preview1 -rfake "  encs

</code></pre>

Attached is the complete output of my rake script.
