Hi,

You're absolutely right. The example you sent me
worked fine (I'm using the same gcc distribution). I
assumed it was a general bug, but it seems it is not.

The library I'm compiling has the problem thou,
programs linked against the dll fail to link because
of undefined static symbols. Doing nm I see they are
not there. The symbols *are* there in the source, also
the static library works fine.

May be gcc got messed up with a bigger library? (this
one has LOTS of .o's, and takes about 20 mins to link
in a fairly fast machine...).

I have tryed several combinations of dllwrap and gcc
-shared with different flags. I'll try to check all
this with care, something is messed up (hope it's not
ME :-).

A question: What is the supposed instalation hierarchy
for the files distributed on sourceforge? I unpacked
all of them in c:/mingw32, but ld fails to find
crt2.o, I had to manually modify lib/gcc-lib/.../specs
file.

Thanks for your answer,

-cristian
