[Zamrony P. Juhara]

custfcgi.pp and fpfcgi.pp both directly /indirectly depends on fastcgi unit.

This unit is a translation of a library. Most likely, that was exactly the
value specified in the original header files.

I would not recommend using this unit. 
It is most likely outdated, and I would not even know what library it supports. 
I will ask on the core group what to do, I think it is better to remove it.

Free Pascal supports fastcgi natively using the custfcgi or fpfcgi units.
