<appname>_PSWRAP_FILES = psfuncts.psw 

is what you need to use in the GNUmakefile for the application.

PSW files are Postscript Wrapper files.   These allow the programmer to define
a function purely in postscript and then run a program called "pswrap
<filename>" to produce the resulting .c file.

NSGraphicContext takes the place of NSDPSContext on MOSX and GNUstep.  
Postscript functions can be found in PSOperators.h.

Not sure why this matters.

Yes there is an equivalent.  A few apps have been ported and are available on
the ftp.gnustep.org server.
