The problem was that both caller and callee removed function argument from
the stack. I have already solved this situation - I had to use MS C compiler
and linker.

The InterBase client library gds32.dll exports the functions with names as
isc_dsql_describe etc., but the functions are compiled with __stdcall
convention (there are no @xy suffixes). When I included the header file with
stdcall set for the functions, I have got .o file. But this file must be
linked with functions isc_...@xy from the import library. But when I created
the import library with isc_...@xy functions that functions were not found
in the DLL.

So is there any possibility in gcc to create the .o file where stdcall
functions will not have @xy suffix? Or is there a possibility to link
stdcall functions (with @xy suffix) with functions from import library
without @xy suffix?
