spin2cpp build problem

I've been away for a while and decided to update spin2cpp to the latest code. I did a "git pull" but when I type "make" I get the following error: 
dbetz@Davids-Mac-mini-2 spin2cpp % make
bison -t -b ./build/spin -d frontends/spin/spin.y
frontends/spin/spin.y:7.9-18: syntax error, unexpected identifier, expecting string
make: *** [build/spin.tab.h] Error 1
This is when attempting to build on the Mac with the Xcode command line tools.

    It looks like you'll need a newer version of bison. I can't build on my Mac right now because after I upgraded Xcode stopped working, but my Mac mini can't be upgraded to the Mac OS that the newest Xcode needs, so for now I'm stuck :(. But probably there's some way to get a stand-alone version of bison. If all else fails you can probably build it from source.

    I used brew to install a new version if bison and got spin2cpp to build with the following commands: 
    dbetz@Davids-Mac-mini-2 spin2cpp % export PATH=/usr/local/opt/bison/bin:$PATH 
dbetz@Davids-Mac-mini-2 spin2cpp % make
    However, I ran into a warning. Not sure why Xcode is complaining about this though.

    That last warning seems to be about gcc taking "if (( a = b))" (double parentheses) as a hint from the programmer that 'yes, I really meant to use "=", not "==" here.' So, gcc gives a warning for "if (a = b)" but not for "if ((a == b))" (this convention is not followed by every other non-gcc compiler, but some do)). So, gcc then decides to throw a warning if you use "if ((a == b))": "You hinted that you really meant to use just '=' here, but you still use '=='"

    That sounds like a warning that should be turned off! :smile:
