With a command line like this:

>> libtool -dynamic -L/Library/Frameworks/Firefox.framework/Libraries \
>> -lSystem -lib_util -o rfunc.dylib (...) rmd5c.o

it compiles, but, now, I'm not able to export all the
module's symbol. I try to specify a ".def" file with the
object's list to export, but it don't works.

Since "fbudf" build correctly without special "export
macro" (there is a "#define ISC_EXPORT" in the code),
could someone tell me where I'm wrong?

Thank you in advance
