cygwin build_alias issue (and a possible workaround...)

I tried to configure and make all BSPs, just for fun:
../rtems-4.6.1/configure --target=m68k-rtems --disable-posix
--disable-networking --disable-cxx 2>&1 | tee -a log.txt

gmake all 2>&1 | tee -a log.txt

And here comes the error (from gmake all):

This is with the set -x and strace removed from the configure files, but
the Bogdan's expr shell script hack in place.


I forget to check expr.log, so I ran another configure/make round.  This
time it failed in the mrm332 bsp, with the same error message:
