Not having the GNU sh or whatever, but having the MKS sh, I tried setting the 
SHELL var in the makefile to c:\bin\sh, and it ALMOST worked.  When trying out 
'make distclean' in the gcc-263 source directory, it cleaned my entire d: drive 
for me!  Fortunately, I had a tape backup.  OK, so then some more 
experimenting.  Starting MSK sh before invoking the make still didn't help.
When doing things like if ... fi, it would make command.com-like complaints.
Your mention of COMSPEC provided the key, though.  By setting the environment
var COMSPEC=C:\BIN\SH, I was able to start 'make distclean' from the DOS
command.com prompt, and the makefile invoked the MKS versions of sh and rm and 
seems to work OK.  You still need to set the SHELL var in the makefile, so 
after a 'make distclean' and 'configur', you need to edit the makefile, if your 
'sh' is not on the same drive as the build drive.  This, of course, is a real 
band-aid, but any port in a storm, as they say...  Now we'll see if I can
re-compile the compiler for 386 host/target, without the make bombing out.
Previously, it would blow up occasionally with a memory allocation error
(8 MB system, 50 MB free space on hard drive -- I now have a 16MB system with
121MB free for swap)
