The only linux libraries that you can continue to use are the ones that
are linked to the development tools (gcc et all) or dynamically loaded
by the dev tools. For the target executables (ie., your code) CANNOT use
linux libs, but has to link to target libraries. To answer you question,
all of the above.

I have a sneaking suspicion that if you modify your tcl/tk objc code to
use Tcl (de)allocation routines instead of malloc/new/free/delete, your
code will work just fine. (Caveat: this is just a hunch, since most of
the problem seems to due to incompatibility in the memory handling btwn
gnu-win32 and Borland run-time).
