f5022228ba Fixed typeOfSpec to use the recorded type rather than trying to dig it out of the inner expression/variable 2008-02-29 16:33:33 +00:00

8f2575819b Initial implementation of the occam-pi preprocessor. 
This implements #DEFINE, #UNDEF, #IF, #ELSE and #ENDIF, macro expansion with
##, and TRUE, FALSE, AND, OR, NOT and DEFINED within #IF expressions, with the
same semantics as occ21.

The macro COMPILER.TOCK is always defined by default, so you can now say things
like "#IF NOT DEFINED (COMPILER.TOCK) ... #ENDIF".
