Are you discussing *nix or what?  On most systems there is neither
ld.so, nor libdl (and no *.so at all ;-).

Let me make my complaint more explicit: suppose you want to access a
library for same "software package", e.g., FFTquick.  It may be called
libFFTquick.so on *nix systems, and FFTquick.dll for DOSish systems.

The situation is somewhat easier for packages specially designed to
work with PARI, since you have control to name the DLLs contrary to
the system conventions.  However, even in this case there may be
complications.

For example, to ensure compatibility with FAT filesystems, OS/2
*forces* the DLL names to follow 8.3 convention.  So a DLL cannot be
named libFFTquick.so.  Additionally, it may take additional steps to
create DLLs which do not follow the system name-conventions...
