Subject: GNAT corrupted builds with below second changes

Hi,

I'm doing some automated testing that involves very fast file generation 
and recompilation. Platform is linux, GPL 2017 or FSF 7.2. I've observed 
that gprbuild seems to not detect that a file is changed if less than a 
second has elapsed. I will guess here that the timestamp being used has 
second precision. This leads to supposedly up-to-date builds that 
aren't, among other funny effects.

I faintly remember having read about this somewhere, but I'm unable to 
find anything related in web searches. Anyone has experienced this?

Thanks,
Álex.
