I've started evaluating mingw-w32-1.0-bin_i686-mingw_20110422.zip as a 
toolchain where I typically use the 32-bit 4.5.2 version from 
http://tdm-gcc.tdragon.net/

The build environment uses LIBRARY_PATH and works fine with tdm-gcc 4.5.2 but 
fails with the mingw-w64 toolchain because ld can't find some of the libraries.

I'm not done with testing, but it appears that the LIBRARY_PATH issue is the 
root cause of my build failures.  For the mingw-w64 case I inject the name 
prefixed binaries from bin/ into the environment rather than use configure's 
--host; config.log indicates that mingw-w64 isn't cross-compiling.

I've read the https://sourceforge.net/mailarchive/message.php?msg_id=25062006 
thread and would like to know the latest mingw-w64 recommendations for using 
LIBRARY_PATH.  While I would like to be able to use LIBRARY_PATH as I do with 
other MinGW-based toolchains, is there another env var or setting other than -L 
I should be using?
