I've put a version of Make linked with a hacked dosexec.c on my
server, it's available for anon ftp:

   ftp://is.elta.co.il/pub/make_nex.zip

Unzip make.exe and try to use it.  If you set W2KBUG in the
environment (the value is not important), it will toggle exceptions
before invoking child programs.

The diffs against dosexec.c in djlsr203.zip are reproduced below, so
if Someone (tm) can build Bash for Charles, please feel free...
