So what would you expect using a Unix tool ? Cygwin make *has to be* case-sensitive! >A am jusing Cygwin make (in UNIX mode) on a WinNT platform. >Until now I a >have defined all rules explicitly like > >main.o: main.c > gcc -c main.c > >which is case-insensitive regarding the source file.

Is there any particular reason for this >strange behaviour? This is what I would have expectet in *any* case. I reproduced following effects with 2000: Having the files main.c, HELLO.C, and this.c and your makefile above make main.o => Compiles with explicit rule make this.o => Compiles with implicit rule make hello.o => No rule make HELLO.o => Compiles with *predefined* implicit rule make -r HELLO.o => No rule IMHO this differences are by chance. It may depend whether make checks its files with fstat to compare the time stamp or by name using the directory entry. I am sure that both variants are used in make (no, I have not looked at the source). With Unix it does not make any difference, while ftstat will find the file in NT/2000 independent of the case.
