Nico,
I'm moving this to the vmsperl list as there may be others interested
and/or more knowledgeable than me.
cc/names=truncated will not work because the extension-building
mechanism in Perl does its own name shortening, which will be
incompatible with any done by the C compiler. The problem that
arises then is that the expat library does not go through the Perl
extension preprocessor, so there is no automatic way to shorten its
names in a fashion compatible with those in the the extension. The
only workaround is to manually identify the long symbol names shared
between XML::Parser and expat, and then manually whack them into
something shorter but still unique. I think the only way to identify
which symbols is to follow the linker warnings.
I'd like to see us in the future have the option of leaving long
symbol names alone in the extension preprocessor and then let the
C compiler (6.0 or later only) handle the shortening, but as far as I
know no one has looked into this yet.
