Hello,
If my ~/gambcini file contains an include for syntax-case, Xlib fails to build:
/src/gambc-4.0b22/examples/Xlib-simple$ make Xlib.o1 rm -f Xlib.o* ../../gsc/gsc -:=".. /.." -dynamic -cc-options "" -ld-options " -lSM -lICE -L/usr/ X11R6/lib -lX11" Xlib.scm *** ERROR IN map -- invalid syntax () make: *** [Xlib.o1] Error 70 /src/gambc-4.0b22/examples/Xlib-simple$
At the top of syntax-case.scm you will find this comment:
; Since the ; syntax-case expander does not know about Gambit's syntactic ; extensions (like DSSSL parameters) some of the syntactic ; extensions cannot be used. On the other hand, the syntax-case ; expander defines some new special forms, such as "module", ; "alias", and "eval-when".
Basically, when you use syntax-case.scm the portable syntax-case system "takes over" and hides all the Gambit specific special forms and macros, and you get a system that is very close to Chez Scheme (except the set of predefined procedures is different and there are slight differences in lexical syntax).
So with syntax-case.scm, you have to limit yourself to R5RS Scheme code. If you want to mix Gambit specific code, I suggest you put that code in a separate file, compile it, and "load" it as needed. This means that you will have to use define-macro to define macros in your Gambit specific code.
