The probability is that the undefined symbols are not exported because they do not appear in the EXPORTS section of win32\perldll.def. They do not appear there because they are not considered a part of the official PerlApi and not intended for use by code outside of the core.

Under *nix/cygwin, all symbols in a .so are exported by default because there is no mechanism to prevent it. As win32 has a mechanism to prevent the exporting of symbols from .dlls, it is used.

Hence, code that subverts the official API set, builds under *nix/cygwin but not under win32. If you could persuade the p5p guys to export all the symbols in perl5x.dll, regardless of it's official API status, about 90% of the "builds fine on *nix, but not on windoze" problems would disappear over night.

Examine what is said, not who speaks -- Silence betokens consent -- Love the truth but pardon error.

In the absence of evidence, opinion is indistinguishable from prejudice.
