Purpose:
Bug Fix
Description:
The way we were generating Dependencies and .depend files was broken.
If the $srcdir or other macros began with a ".", then it would match
anything and cause problems since it would then overwrite the
beginning of the header file's path.
Solution:
Wrote a Perl script which can handle this type of weirdness better.
It's only used when the environment is a GNU one with a GCC
compiler...
Platforms tested:
Linux
