[Swig-user] can't build after perl upgrade

[Albert V. S. <av...@gm...>]

I have compiled a updated version of Perl (5.8.8) to replace an aged  
version on my box.  All is well and dandy with perl (passing all  
tests), but I can no longer make my swig based project, which worked  
very well with my previous version of perl (5.8.0).  When I compile  
the swig-generate wrap file with gcc and the options  from '`perl - 
MExtUtils::Embed -e ccopts` -fPIC', I get a terrible series of syntax  
errors, which begins as follows:

In file included from LdMax_wrap.cxx:720:

<snip>

This is perl compiled for a 64-bit box, and with threads turned on,  
should that be of any relevance.  Anyone have a suggestion on what  
the issue might be?
