I'm thinking of the same way window procedures are done in Delphi. Allocate
memory blocks for executtion (VirtualAlloc on Windows, dunno what on Linux.
Maybe even malloc would be fine), write delegates there: write machine code
for call instruction + the parameter to function.
I wasn't correct about 32-bit Windows. I mean 32-bit applications for
Windows. No matter what the real processor is as long as it supports 32-bit
applications. For other architectures it would need different call opcode,
for other systems it would need different memory allocation.
I hoped such thing was in some kind of cross-platform library, but brief
googling hasn't given the needed result. Maybe someone else would be more
I personally don't see anything bad in using such hacks except the direct
consiquences of architecture/platform dependance.

If you're thinking what I think you are, then it would be an operating
system dependant, and processor architecture (or at least CPU
bytecode) dependant. Note that some 32 versions of Windows (around
NT4?) could run on non-x86 architectures. Linux can do the same.

The only way see is to use a platform-dependant hack. For 32 bit Windows I
can tell you
how to do it. It should be easy to tweak it to use it on 32 bit Linux.
