+$! P1 if this is ENGINES or ALL, the engines will build, otherwise not.

+$! P2 DEBUG or NODEBUG to compile with or without debugger information.
+$!
+$! P3 VAXC for VAX C
+$! DECC for DEC C
+$! GNUC for GNU C (untested)
+$!
+$! P4 if defined, sets the TCP/IP libraries to use. UCX or TCPIP is

+$! compatibility library. The value must be one of the following:
+$!
+$! UCX for UCX
+$! SOCKETSHR for SOCKETSHR+NETLIB
+$! TCPIP for TCPIP (post UCX)
+$!
+$! P5 if defined, tells the compiler not to use special threads.
