Bug #3248: extension 'tk' is finding tclConfig.sh and tkConfig.sh incorrectly
http://redmine.ruby-lang.org/issues/show/3248

Author: Luis Lavena
Status: Open, Priority: Normal
Target version: 1.9.x
ruby -v: Revision: 27624

Using GCC 3.4.5, under MinGW, with msysGit installed, extension tk is finding tcl and tk config bash scripts even when those are not in the path:

<pre><code>
compiling tk
check functions.........
check struct members..
Use ActiveTcl libraries (if available).
Search tclConfig.sh and tkConfig.sh.............................................
Valid tclConfig.sh and tkConfig.sh are found in ["c:/Users/Luis/Tools/Git/lib"]
Use [tclConfig.sh,tkConfig.sh] == ['c:/Users/Luis/Tools/Git/lib/tclConfig.sh','c:/Users/Luis/Tools/Git/lib/tkConfig.sh']
Search Tcl library..
Found a Tcl library at c:/Users/Luis/Tools/Git/lib.
Search Tk library..
Found a Tk library at c:/Users/Luis/Tools/Git/lib.
</pre></code>

This is using a subversion checkout, not a git checkout and a normal command prompt (instead of bash).

Attached are config.log, config.status and mkmf.log from the ext build directory for tk extension.

Steps to reproduce require Windows, subversion, Git and a clone of RubyInstaller build recipes.
(of course, a working Ruby 1.8.6 or 1.8.7 is required too).
