make win32 doesn't correctly handle canned sequences.

[Scott Carter <scarter at emware dot com>]

make --win32 does not correctly handle canned sequences (AKA 
multi-line, recursively-expanded variables, which are 
created with the "define/endef" directive). It appears that 
perhaps the memory which holds the canned sequence is being 
overwritten/corrupted.

The problem occurs with the Cygwin port of gnu make, 
versions 3.77, 3.79, and 3.79-2 (maybe others), but only 
in win32 mode (i.e., make --win32 ... OR 
set MAKE_MODE=win32 ...).

I've written a simple makefile (see below) which 
demonstrates the problem. Also below is a transcript of a 
session which shows the problem, and provides info on 
versions, etc.

PS - Let me say thanks for your quick response on the 
last problem I reported (make win32 chokes on lone tab; 
23Jun2000). I never expected to have the problem fixed 
literally overnight. Great job! I downloaded make 3.79-2 and 
it seems to have solved the lone tab problem (on WinNT and 
Win98). And, I'm sorry I didn't get this one in sooner -- 
it might have saved you a release.
