Bug #3655: Win7/MinGW build fail on trunk at 28857
http://redmine.ruby-lang.org/issues/show/3655

Author: Jon Forums
Status: Open, Priority: Normal
Category: build, Target version: 1.9.x
ruby -v: built with ruby 1.8.7 (2010-06-23 patchlevel 299) [i386-mingw32]

When using MSYS + MinGW 4.5.0 (TDM-based) on Win7 Ultimate 32-bit I get the following failure.  This build error does not occur on the ruby_1_9_2 branch.

./configure --enable-shared --disable-install-doc --with-baseruby="c:/ruby187/bin/ruby.exe" --prefix="c:/ruby_trunk_test"
