change in nightly build breakage

[<don...@is...>]

I presume related to the only change since yesterday:

On the 32 bit single core fedora core 4 machine nothing changed:
- non-mt build works,
- mt build fails ending with
 base/lisp.run -B . -M base/lispinit.mem -norc -q -i i18n/i18n -i syscalls/posix -i regexp/regexp -i readline/readline -x (saveinitmem "base/lispinit.mem")

 *** - handle_fault error2 ! address = 0x1 not in [0x21dd6004,0x21f32524) !
 SIGSEGV cannot be cured. Fault address = 0x1.

- mt build with no dynamic modules works

However, on the 64 bit dual core fedora 11 machine
- non-mt still works
- mt now fails ending with
 base/lisp.run -B . -M base/lispinit.mem -norc -q -i i18n/i18n -i syscalls/posix -i regexp/regexp -i readline/readline -x (saveinitmem "base/lispinit.mem")
