There are four versions of the FastThreads library here:

thread.a -- baseline, no profiling, no debugging
thread_d.a -- debugging (-g, consistency checks), no profiling
thread_p.a -- profiling with quartz, no debugging
thread_dp.a -- debugging and profiling

crt0.o must be used for the profiling versions, and is optional
for the others.  The lint library is the same for all versions.

There are four versions of the Presto library here

libpresto.a -- baseline, no profiling, no debugging
libpresto_d.a -- debugging (-g, consistency checks), no profiling
libpresto_p.a -- profiling with quartz, no debugging
libpresto_dp.a -- debugging and profiling

When compiled for quartz, you must also link in the quartz runtime library:

qlib.a -- no debugging
qlib_d.a -- debugging
