No. What I'm trying to say: When using Mod-Perl2 on win32 your modules have to be thread-safe because you don't have the possibility to use prefork(like on Unix) because it simply doesn't exists as a processing module for apache2 on win32.
Hence on win32 you need a perl with ithreads-support. On your freebsd you could turn of threads when running apache2 with prefork.
=> Setup on win32: ~ + perl with ithreads ~ + apache2 with win32-mpm => Setup on freebsd: ~ => A ~ + perl with ithreads ~ + apache2 with worker-mpm ~ => B: ~ + perl without ithreads ~ + apache2 with prefork
