In a former mail (not yet in mailing list archive) I showed a way to do
this. Open /Pi3Web/Conf/Config.Pi3 and make the following changes:

1.) Default handler
Search for
        Handle Condition="&and(&not(&dblookup(response,string,ObjectMap)),\
&not(&regexp('internal/*',$c)))" SendFile

Insert the following line before it
	Handle
Condition="&or(&cmp($c,text/x-perl),&and(&cmp($c,application/octet-stream),\
&regexp('*.exe',$z)))" CGIScripts

2.) Insert a new handler object named 'CGIScripts'

<Object>
	Name CGIScripts
	Class FlexibleHandlerClass
	Condition "$and($c,&dbreplace(response,rfc822,Content-Type,''))"
	CheckPath RefuseFileByMask AllowFileMask="EFD" RefuseStatus=404
	CheckPath RefuseFileByMask AllowFileMask="F" RefuseStatus=403
	CheckPath ReturnCode ReturnCode=COMPLETED
	CheckAccess AccessByFile RequirePermissions="X"
	CheckType ReturnCode ReturnCode=COMPLETED
	Handle StandardCGI
</Object>

Explanation:
The 'CGIScripts' handler is an exact copy of the 'Scripts' handler for
Standard CGI except of the condition. It is a bit tricky way to delete
the Content-Type of the HTTP-Response Header since this field has to be
filled by the called script.
With this configuration every .pl, .cgi or .exe file is executed when it
is handled by the default handler (With other words - if the request was
dispatched to the PathMapper).

Discussion:
It is possible to extend this for other mime types too. I made an CGI
implementation of PHP3 (version 3.0.3, older version are a bit different)
in that way, the core is only 1 additional line in the default handler:

<Object>
	Name Default
	Class FlexibleHandlerClass
	...
	Handle Condition="&cmp($c,text/x-php3)" CGIScripts
	...

- register mime type for php3 files:

<Object>
	Name HTTPLogicObject
	Class HTTPDispatcherClass
	...
	AddMIMEEntry "php3	text/x-php3"
	...

- conditional execution of PHP3.EXE in standard CGI handler:

<Object>
	Name StandardCGI
	Class CGIClass
	...
	CommandLineByExt .php3="php.exe %p%q"
	...

Hope I don't forget anything. Still questions?
