I agree.  My gdb cannot show variables in 32-bit binaries (or maybe it's
just something Wine specific), but it shows the line numbers.  I traced
find_symbol() in preloader.c, and it seems like symtabend is 0, so that
the last loop is skipped and NULL is returned.  This is also evidenced
by the lack of "Found" in the log I sent in the previous message.

$ nm loader/wine-pthread | grep wine_main_preload_info

Apart from the custom kernel, that's all from the current Fedora
Development:

gcc (GCC) 4.1.1 20060721 (Red Hat 4.1.1-13)
GNU ld version 2.17.50.0.3-2 20060715

It's a x86_64 system, but I have the necessary packages for i386
development.  I don't have SELinux enabled.
