# -rdynamic is to generate debug info for dynamic symbols on debian-based 
# systems (tested on Linux Mint)
# for OSX, using -g generates a newgame.dSYS directory which has debug symbols.
# However, this has no effect on the stack trace, so there must be a way to specify a *.dSYS directory when running ./newgame
# or to instead put thos symbols directly into the executable, like -rdynamic does for Linux
