[Gc] gc make fail on Solaris 10 x86_64 with gcc-3.* & -m64 option

[Kiyoshi KANAZAWA]

Hi, Ivan,

I may encountered some problem again with "release" branch.

"Segmentation Fault" happened in building guile-2.0.5 with -m64 option.

It seems to happen in os_dep.c of GC function:
What I checked is:
% pwd
/tmp/guile-2.0.5/libguile/.libs 
% ldd guile
        libguile-2.0.so.22 =>    /tmp/guile-2.0.5/libguile/.libs/libguile-2.0.so.22

        libgen.so.1 =>   /usr/lib/amd64/libgen.so.1

libpthread.so.1 is linked to /usr/lib/amd64/libpthread.so.1 in the 3rd line.
Is this strange ?

% dbx guile

Do you have any suggestion ?
