OK, will try to reactivate my sourceforge status. Something changed
over the summer. In the meantime, here is what needs doing:
./configure --enable-debug && make
cd unixport
make raw_pre_gcl
gdb raw_pre_gcl
(gdb) b sfasli.c:65
(gdb) r ./
(gdb) cond 1 strstr(q[u]->name,"srget")
(gdb) c
(gdb) p q[u]->name
(gdb) p q[u]->section->name
(gdb) p q[u]->flags
Thanks!

The one in the GCL sources should be fine.
