[cfe-dev] MacRuby issues

[रजनीश]

MacRuby Rakefile passes -fno-common twice when compiling ext directory.
May be clang can strip out duplicate entries before passing it to  
clang-cc.

~/Developer/MacRuby/ext/bigdecimal-> clang -I. -I../../.ext/include/ 
universal-darwin9.0 -I..//.././include -I..//.././ext/bigdecimal - 
DRUBY_EXTCONF_H=\"extconf.h\"  -fno-common -fno-common -pipe -O2 -g - 
Wall -Wno-parentheses -arch i386 -o bigdecimal.o -c bigdecimal.c
clang: warning: argument unused during compilation: '-Wno-parentheses'
clang-cc: for the -fno-common option: : may only occur zero or one  
times!


Also MacRuby currently doesn't compile in x86_64 arch when it uses  
miniruby to run
/usr/bin/make on the ext directory.  It basically segments faults while
running this command.  i386 runs this just fine so does gcc.  may be  
it is bad code generation.

GC_DISABLE=1 ./miniruby -I./lib -I.ext/common -I./- -r./ext/purelib.rb  
ext/extmk.rb --make="/usr/bin/make" --dest-dir="" --extout=".ext" -- 
mflags="" --make-flags="" --extension --extstatic
