Those. Additionally gnatmake is being used in GCC build process when Ada is included.
Use of freshly build gnatmake.exe failed in GCC build process when trying to build other Ada
related tools. The reason was that file name regularization code in s-os_lib.adb put drive letter
in front of DJGPP special directory names: in my case /dev/g/.. became g:/dev/g/..., what did not
work,

BTW, although this isn't definitive proof that gnatmake itself is totally deprecated, I somehow get that feeling. And in case it wasn't obvious, gprbuild is not included in the DJGPP port. (It is allegedly GPL'd on AdaCore, though, so perhaps FSF hasn't bundled it yet??)
It says that 'gnatmake -P' is obsolete, bit gnatmake itself and suggests to use gprbuild.
There is no file gprbuild.exe in my build of gcc-5.3.0 for DJGPP. Strange but it is not present
also in earlier build of gcc-6.0.0 20160126 for both DJGPP and Linux and also for Linux to DJGPP
cross-compiler. One could expect to find it there when there is such message fromgcc-5.3 gnatmake.

I guess that gnatmake -P support could be whats broken. I do not know that however for sure.
