Old version/format of libmysql.lib (linking fails)?

Hi everybody,

I'm trying to access MySQL from an application which is written with
Openstep 4.2 for Windows (uses Objective-C with gcc 2.7). I'm using
the C api from MySQL and could compile a first test but I get an error
during linking regarding the libmysql.lib: "fatal error LNK 1106.
invalid file or disk full. Cannot seek to xxx".
As far as I know it has to do with the fornat of the lib - gcc 2.7
only supports older lib versions (VC5) and the mysql lib is in VC6? I
could not find someone who has ported a newer version of gcc to
Openstep so I think I need the libmysql.lib in the older format. I
know that there's a compiler option "-link50compat" which should have
the effect that libs are created in the old format.
Is anybody out there who has tried this and/or could help me regarding
this (maybe with an appropriate lib)?

Thank you very much and best regards

Matthias
