Okey. Please test the following and let me know if it
works? Since I have no access to i386-elf system, I'm not
sure that this actually works on ELF system, though (it
works for me on i386/1.4.1).
1 replace boehm-gc/patches/patch-ac with the attached diff.
2 make makapatchsum && make
3 cd ${WRKDIR}/gc and do the following:
 ./test_cpp 1 2>/dev/null&&echo ok
