Well, I sort of know what I'm looking for, so this is cheating-ish, but: $ grep ' SP ' *.h | grep define XSUB.h:#define dITEMS I32 items = SP - MARK pp.h:#define SP sp > > In the c-MSWin32.visualc.h file in the hints folder of the perl Curses-1.15 > source I found this (provided by Gurusamy Sarathy): > > #undef SP /* in case this gets pulled in after perl.h */ > > But that doesn't help me much.

I think you need to stop that Perl macro being in force at the time you're using the curses macro. Nicholas Clark
