Made the changes you specify below & re-ran "make install". Attached
is the log from the latest strace.

Incidentally, I've tried this on two other machines at work with the
same results. The steps to reproduce are annoyingly simple: download
cygwin installer & execute (accept all defaults), select the packages
specified for the binary windows install on the git wiki, try to
create a git repository and add files. Frustrating - especially since
my desktop at my last job worked just fine.
