Summary: zexy dlls don't load from Pd-0.40.3 windowsxp

Initial Comment:
zexy dlls from the nightly autobuilds don't load but abstractions do.

Zexy's README.txt says:

configure tries to set the CFLAGS to "-g -O2" if the compiler accepts this; however, this optimization sometimes generates binaries that cannot be loaded by pd; it seems that disabling the "unit-at-a-time" optimization (which gets enabled by "-O2") is the cause of this problem, turning it off might help

This seems to be the case here. The log from 2008-03-12_05.54.05_mingw32_nt-5.1_windowsxp-i386_pd-extended_run-automated-builder.txt has:
gcc -I.  -DHAVE_CONFIG_H  -DPD  -I/home/pd/auto-build/pd-extended/pd/src  -g -O2 -mms-bitfields -fPIC -mfpmath=sse -msse  -c -o 0x260x260x7e.o 0x260x260x7e.c

the problem seems to be the linker-flag "-export_dynamic"; without this
flag, externals load just fine.

hmm, i have to think about this...

weird: when i manually build a zexy-object on the buildform machine (XP),
they work fine (with exactly the same flags as i see in the autobuild-logs)
