( ./configure ; cd boehm_gc ; make gctest_dyn_link )

Results in a link error.

( ./configure ; cd boehm_gc ; make sunos5gc.so ; make gctest_dyn_link )

Compiles, but running the executable gctest_dyn_link results in core being
dumped. (Note: this occurs even if LD_LIBRARY_PATH includes the directory
containing the shared library version of the garbage collector).

Host: quirk (my home computer)
./gctest_dyn_link 
Segmentation fault (core dumped)

Host: capricciosa (CS's 'test' machine)
./gctest_dyn_link 
List reversal produced incorrect list - collector is broken
Abort (core dumped)

I am assuming that this should actually run the test, and that merely
compiling it is not sufficient. Anyway, hope this helps somewhat.
