PAR 0.86 has some changes to eliminate redundant unpacking, but that means that any DLL  
that is loaded indirectly by another DLL, rather than loaded by a Perl module needs to 
be packed with the -l option so it will be packed in a shared lib directory and 
unpacked into the temp directory next to the DLL that loads it, where it can be found.

	pp -l <full_path>/wxmsw252u_adv_vc_custom.dll -o minwx.exe minimal.pl
