[PD] compiling flext external

Hi Yvan,
i don't have the C++ builder at hand, but i can confirm that the free 
BCC++ 5.5 needs special treatment, which might also be necessary for 
newer Borland products.
This means that you could have to pass the linker a .def file containing

EXPORTS lib1_setup=_lib1setup

I don't understand why it wants lib1_setup when your function is called 
lib_setup, though.

Additionally the old BCC++ 5.5 can't deal with COFF libraries which 
means that i have to convert them using implib. I'm pretty sure that at 
least this has changed in the meantime. Maybe i try the C++ builder 
demo version when there's time to.

best greetings,
