Peter,
ActivePerl is compiled with the PERL_OBJECT option to accommodate
ActiveState addon products like PerlScript, PerlEx etc. This requires C++
which is not compatible with MSC++ 4.2 anymore. I tried unsuccessfully to
fix this, but 4.2 unfortunately doesn't grok the required predeclarations
for the CPerl object, you have to define it, which you can't, because some
required types are not yet defined; a circular reference.
You have to update to MSC++ 5.0 to compile Perl 5.005 with PERL_OBJECT
enabled, but standard build still compiles with 4.2, so you can recompile
from the sources if you don't use the other ActiveState gadgets. Then you
can also compile the extensions with 4.2.
