[fpc-devel] profiling on win32

[Lee, John]

Guilio 

Why not zip all the files needed, add a short readme with your name & email address, and I'll then put it onto ftp.freepascal.org  /contribs in a directory called win32_prof or something similar? 
Email me directly (leej at logica.com) if you can do this & I'll give you an upload ftp address for the zip. 

Regards John
