I see that there is a new test which tests for GNU make.  How solid is 
it?  For example, the GNU make I use under MinGW is called 'csmake' 
(for "Case Sensitive make") because the default MinGW GNU 
case-insensitive make is horrendously slow, taking a couple of minutes 
before it does anything at all.  It seems that someone decided that 
MinGW make needs to be case-insensitive and it operates via 
brute-force, trying every case permutation.  If a network is involved, 
this becomes frightfully slow.  As a result, whever I would normally 
type 'make' I type 'csmake' instead.
