Yes - my current list of preferences is
- See how ExtUtils::CChecker fares, especially concerning speed per checked symbol and the compatibility wishes of Maddingue. Currently Net::Pcap claims to be compatible back to Perl 5.004, and this build prerequisite will likely break that.
- See whether I can coax DynaLoader into providing a list of symbols. On Win32, DynaLoader is basically LoadLibrary() and GetProcAddress() anyway.
- Parse the output of nm or dumpbin.exe to get at the list of exported symbols. This has the attractive feature of allowing to find the symbols not only of DLLs but also of .a and .o files.
