As Rob mentioned, it's unlikely you'll be able to use gcc
in compiling a program and linking it to a lib compiled
with VC++ 6. But in any case, those functions are contained
in perl58.lib (in C:\Perl\lib\CORE), which will in turn
invoke perl58.dll (in C:\Perl\bin). You can see them
explicitly by doing a
   C:\Perl\bin>  dumpbin /exports perl58.dll | grep ppaddr
(assuming you have a 'grep' utility), where 'dumpbin' is
a VC++ tool.

Probably the safest option you have is to compile Perl
yourself, either with gcc or with the free version of VC++
7; with gcc you'll lose binary compatibility with
ActivePerl, and with VC++ 7 there may be problems in certain
circumstances with binary compatibility (search the list
archives to see some discussions on this point).
