    3030My '''real''' introduction to GNU make came when working on GCC for OS/2 and the !InnoTek LIBC (now kLIBC) where Andrew wrote some really cute makefiles which I ended up having to maintain. This including having to fix them so they would work with the various GNU make 3.81 alphas and betas, and to change them to use new features in 3.81 that allowed me to do the makefile generation in memory rather than on disk. I found the defines and functions concepts intriguing after the feature starved NMAKE world and not being able to kick BSD make into doing everything I wished for.

    32 Another thing I realized (once again) working on kLIBC and GCC was that makefiles usually ends up depending on external tools other than just the compiler, linker and librarian. I've lost count on how many times I've had to help figuring out weird build breaks which was caused by a different shell, an innocent environment variable, different sed or gawk, a broken tr, or similar stupid things. And this was just on one single platform with kind of low activity. Now thing going for crossplatform... So, a cross platform framework must try provide similar behavior on all platforms. The simplest way of doing that is naturally to provide all the tool it uses, and do the necessary changes to force them to behave correctly.

    3434When I restarted the work on a make framework back in 2004 the obvious choice was to use GNU make 3.81 for the makefiles. For the other tools I usually prefer the BSD version over the GNU one because the BSD code is usually simpler, has less dependencies and is easier to port (to Windows). That is, if the BSD version exist and provides the necessary features (SED didn't and therefore it's GNU).
