We use it, a multi path TCP router written in C++ and behind
there is a Postgresql...

You also have long doubles on some compilers which could be 80 bit.
Actually, they're
The compilers from Microsoft and Borland atleast aren't
compatible.
But that shows up as link errors, not at runtime, right?
Correct. Microsoft and Borland use different library packaging formats,
COFF and OMF. However (non C++) DLLs are compatible and you can extract

Good point. There's standards, and then there's Windows. It's possible
that separate tight-packing and regular pragmas are used there, just
for structs that are expected to be

The C language does not define alignment of structs.
Platform ABI standards do, though (hence the as long as it adheres to...
clause in my previous post). Whether it's in the C language or in the

I am having some trouble
I am having some trouble interfacing the 7.5 server built with MINGW
with tools generated using other compilers.
I suspect that the issue is one of default structure packing. In the
old version we were using, we built PostgreSQL using Intel C++ or MS
VC++ and the same for the libpq and other
