Marc:
Have you ever managed to build Gambit configured with
./configure --enable-coverage
??? I killed my attempt when cc1 for lib/_io.c got up to 25GB RAM and
most of the rest of my system was swapped out. (This is on a Ubuntu
14.10 system with the built-in gcc-4.9.1.)
Also, please move gsc/_t-univ.c to the beginning of the list of source
files in gsc/makefile; it's by now the biggest (by far) source file in
the gsc directory.
