Hello Paul,

I'm in the process of bootstrapping your branch on Windows using Msys+Mingw32,
the ./prepare.sh script worked fine,
But I got a parsing error for Mmake.common at BOEHM_CFLAGS_FOR_THREADS,
there was a spurious newline. Traced it back to autoconf.ac, please
see the attached diff.



PS: Good luck for your surgery
