There is a new version of extern_symbols.p
    http://www.cs.bham.ac.uk/research/poplog/src/new/extern_symbols.p

which replaces this one:
    http://www.cs.bham.ac.uk/research/poplog/src/new/extern_symbols.p.orig

The change alters the definition of DLOPEN_FLAGS for linux thus

    #_ELSEIF DEF LINUX_ELF
    lconstant macro DLOPEN_FLAGS = 16:101;  ;;; RTLD_LAZY|RTLD_GLOBAL

In the original file the definition was
    lconstant macro DLOPEN_FLAGS = 16:001;  ;;; RTLD_LAZY

(as in the Solaris version).

This fixes a problem that externally loading more than one shareable
dynamic library did not allow symbols used in one to be defined in
another, whereas that is now fixed.

Many thanks to David Young and Jeff Best for help in identifying the
problem and finding the likely place to fix it.

I hope to have newly built versions of the linux poplog tar files
soon.
