...not any _additional_ C library. If the C library is already
(statically) linked into the main executable, the loaded bytecode can
use it.

From "configure" I guess that the following platforms can load, and any
other cannot: all Win32 (incl Cygwin and MinGW), Linux, FreeBSD,
OpenBSD, NetBSD, DEC alpha, Solaris, IRIX, Mac OS X. The others are
nowadays very exotic (e.g. HP-UX), or special (e.g. the iOS support I'm
preparing in a separate patch won't include dll support - Apple does not
permit apps to use shared libraries).
