[R-SIG-Mac] Trouble building R 1.7.1

[Simon Urbanek]

As Thomas pointed out this was an issue a while ago. This is a part of  
post I sent at that time:
(the proposed solution refers to the relevant #include in devQuartz.c)

I was just building R-devel with aqua today. I had some issues  
compiling it, so I'm letting you know ... just in case ... ;)

gcc -no-cpp-precomp -I. -I../../src/include  
-I../../../../R-devel/src/include -I/usr/X11R6/include  
-I/usr/local/include -DHAVE_CONFIG_H   -g -O2 -c  
../../../../R-devel/src/unix/devQuartz.c -o devQuartz.o
In file included from  
/System/Library/Frameworks/CoreServices.framework/Frameworks/ 
CarbonCore.framework/Headers/CarbonCore.h:113,
                  from  
/System/Library/Frameworks/CoreServices.framework/Headers/ 
CoreServices.h:21,
                  from  
/System/Library/Frameworks/Carbon.framework/Headers/Carbon.h:20,
                  from ../../../../R-devel/src/unix/devQuartz.c:35:
/System/Library/Frameworks/CoreServices.framework/Frameworks/ 
CarbonCore.framework/Headers/Debugging.h:285:2: #else without #if
/System/Library/Frameworks/CoreServices.framework/Frameworks/ 
CarbonCore.framework/Headers/Debugging.h:287:2: #endif without #if

../../../../R-devel/src/unix/devQuartz.c:922:1: unterminated #if
make[3]: *** [devQuartz.o] Error 1

This is mainly due to the fact that R uses DEBUG in some way where  
Carbon expects it to be either undefined or defined as 0/1. Dirty fix  
is to always #undef it before including Carbon.h, but that is just a  
quick hack, not a real solution. A bit more general (but clumsy) is the  
following:

#ifdef DEBUG
#define __R_DEBUG DEBUG
#undef DEBUG
#endif
#include <Carbon/Carbon.h>
#ifdef __R_DEBUG
#define DEBUG __R_DEBUG
#undef __R_DEBUG
#endif

that works for me ... although I'm still not happy about R using DEBUG  
... I fell into that trap with Rserve already.

... and as Thomas also pointed out this was fixed in R-devel since.

Cheers,
Simon
