I played around last night... pity I don't know dlls that well :-]

1) the ltdll.c header seems unneeded with current gcc
gcc -shared -g -O2 -Wall,--enable-auto-image-base,--out-imp-lib=.libs/libnam
e.dll.a -o .libs/libname.dll -export-dynamic a.lo b.lo c.lo

built a dll quite happily from standard sources except there were no
exports...
I presume that's what the sed and DLLTOOL scripts in the current libtool are
all about? generating a .def file to explicitly list the exports?

2) the .def files format was broken
-> I haven't looked at this yet

3) the .def file had many un-related symbols pulled via dlltool and sed.
(i.e. printf as an export from glib...)
I'm kicking around using NM and searching for T entries in the .lo files
rather than libtool --export-all

comments anyone?

Rob
