Bad idea: it should be 'false'.  Git should not change the EOLs,
neither when it checks out files, nor when it pushes them upstream.

I'm not sure this is the root cause of your problem, but it might be.
Suggest to reconfigure Git, and then delete your local repository and
clone it again.

When you install Git, it asks you how you want to treat EOLs, and you
should have selected "checkout as-is, checkin as-is" (or somesuch, I
don't remember the exact wording).

Not for MinGW, for MSYS.  The autotools you run are MSYS tools, and
MSYS is a fork of Cygwin; Cygwin tools expect Unix-style EOLs, yes.
They could definitely choke if they see Windows-style CRLF EOLs.
