To be honest, the support is not so good as with some other platforms, there are several known issues and limitations. One of the problematic areas are limitations related to the ancient EMX (GNU) ld linker (and also other parts of the GNU toolchain like the debugger); it would be better to switch to another linker, but that is a non-trivial task, unfortunately, because it implies many changes also in other areas). One additional area is the well-known 32-bit/16-bit thunking (support of a special calling convention necessary for invoking some of the old 16-bit API still used for console support is not available in FPC, but that is solvable using wrapper DLL like emxwrap.dll). Finally, some parts of the RTL are not debugged that well (or not even finished completely) and some FCL packages have not been ported to OS/2 yet. I'm willing to assist in solving these areas, but my time available for FPC is unfortunately rather limited and thus the progress is very slow.
