+ Added -inc support for lib dependencies. This means that
changed libs will also force a target rebuild.
I've implemented three separate logic for mingw/cygwin,
gcc/linux+sunos and the rest of compilers. This may not
be precisely the way each of the hbmk2 supported compilers
wotk, but it probably covers most cases. Anyhow please
tweak and correct if you find some problems. I did
tests with mingw, msvc, bcc static and shared mode.
! Removed automatic path tweak in .hbp/libpaths=.
