I thought the change had been to preserve prior TryCompiles for
debugging purposes.
Would it be too cynical to propose some OS #ifdefs above the code?
Although you mention file systems, so this an NTFS issue also?
Of course, at the end of the day this is what breaks GNAT TryCompile:
- targetName = "cmTryCompileExec";
But not removing that line of code would seemingly break everything else.
So the path of least resistance cynical code change proposal:
#ifdef __linux__
targetNameBuf = "cmTryCompileExec";
#else
sprintf(targetNameBuf, "cmTryCompileExec%u",
cmSystemTools::RandomSeed());
#endif
With a nice comment like "so this annoying coding language Ada and its
terribly conceived compiler GNAT can be supported on Linux" or some such.

I could get into details, but the short summary is that gcc-gnat is a
very headache-inducing compiler with poorly conceived input/output file
behavior and arguments.
The change in question is here:
http://cmake.org/gitweb?p=cmake.git;a=commitdiff;h=4fbdce2b
It was done to try to work around problems on Windows tools and
filesystems. You can try hacking the change further to test a
platform variable so it can be disabled for Ada tools. If you
get it working we can put that change upstream.
