Trying this on ix86 Linux, I got it compile, but after starting my
program I got the following segfault:

Program received signal SIGSEGV, Segmentation fault.
0x400bbcc9 in scm_the_root_module () at modules.c:70
70        return SCM_CDR (the_root_module);
(gdb) bt

Note, I just replaced my call to gh_enter(..); with
scm_init_guile(); main();

Also linking with guile configured without --with-treads does not
work, as some qt_ symbols are undefined - seems to be soemthing
is using qthreads even if they are not configured.
