Seems like a problem with SHELL = /bin/sh or something like that.  See 
below.

Make crashes because of a bug in library function `system' which was 
fixed in CVS in April.  The bug would raise its ugly head when Make 
invoked a command that uses pipes and which fails half-way through the 
pipe.  This typically happens when a command that was supposed to be run 
by Bash is instead run by the internal emulator of COMMAND.COM, which 
doesn't understand the syntax of Unixy shell. 

One case when Make cannot invoke Bash is when something happens to PATH.  
This causes the "SHELL = /bin/sh" line in a Makefile to be effectively 
ignored.

The last two lines are a telltale sign of the failure I described above: 
either COMMAND.COM or the internal emulator is trying to run commands 
meant for Bash, and Make crashes due to a bug in `system'.

Fixing the bug won't fix the problem, except that Make won't crash; but 
the build will still fail.  Try to find the reason why Make doesn't 
invoke Bash, like it should.
