I've been having problems with gprof. When I try to profile a program
using the -pg profiling switch and linking with the profiling libraries,
the resulting executable generates a correct call graph, but all of
the procedure execution times are marked as zero. I've probed things
a little deeper and it appears than the mc_chain 18Hz timer interrupt
is never being called. gcrt0.o appears to install the vector correctly
(but then I've a x86 novice with years of 68K experience) yet the
interrupt handler is never called.

Is this a known problem? Is go32's mc_chain hardware or configuration
dependent? Anyone got any ideas?...
