This seems reasonable; but how does it interact with the fact that cfg.mk 
currently defines the make macro _autoreconf to remove INSTALL?  I think that 
definition also needs conditioning (ie. if on a case-insensitive make, it seems 
like cfg.mk must not redefine _autoreconf from its default in GNUmakefile).

Other than my nit about _autoreconf, I don't see any technical flaws in your 
patch.  But I'd feel a lot more comfortable if someone actually tested your 
patch on the case-insensitive MSYS make (or at least the algorithm in the .m4 
file) to ensure that we will correctly detect the situation, before applying 
this patch.
