We're just typing 'make', which unless something changed, should be the 
same as 'make --unix'.  'make -p | grep MAKE_MODE' returns 'MAKE_MODE = 
unix'.  Hmm.  I do see that /etc/profile is setting MAKE_MODE=unix so 
that may not be make's default.

That example works fine if I do 'make --win32' but fails when just using 
'make'.  That is a change in behavior from the previous version of make. 
  The testcase works with either of --unix & --win32 when using make 
3.79.1-7 .

Using --win32 is not an option for building Mozilla as the common set of 
build rules assume that a bourne shell is being used.
