I'm unsure if this is a binutils-specific issue or not, since I'm told that gcc-related projects use their own configuration environment. But I noticed the following when attempting to compile binutils...
config.h was not being created correctly on my Windows 7 (x86_64) machine using
the latest released tools from msys/mingw, causing all sorts of build problems.
After investigating the issue, it was narrowed down to a problem with how
config.status produces and then uses defines.awk. That awk file uses a regular
expression that looks for lines like "#undef VALUE_HERE" to eventually change
them to "#define VALUE_HERE 1" if configure deems it so, but it wasn't finding
them due to mismatches from Windows-style line endings.
This patch (attached as well) fixes the issue in defines.awk, but I'm unsure of
where it really needs to go (because defines.awk is created by config.status,
itself created through configure) since I'm not an autotools expert:

Perusing the repo., it seems that the fix could go here (but again, I'm unsure
due to lack of experience):

Hope this helps.
