Hello,

Compiling Gem on OSX 10.9 is littered with these errors:

"error: addition of default argument on redeclaration makes this constructor a default constructor"

There is discussion about this here:
http://stackoverflow.com/questions/18313509/default-argument-gcc-vs-clang

I understand what is happening but I do not know how to properly fix this. For example if in:

src/Controls/gemlist_info.cpp ->
gemlist_info :: gemlist_info  (t_floatarg arg0=0) {


src/Controls/gemlist_info.h ->


gemlist_info (t_floatarg);  // CON



I am able to compile without error if I do:

src/Controls/gemlist_info.cpp ->
gemlist_info :: gemlist_info  (t_floatarg) {


src/Controls/gemlist_info.h ->
g
emlist_info (t_floatarg arg0=0);  // CON


BUT in a more complicated example where there might be (t_floatarg arg0=0, t_floatarg arg1=0, t_floatarg arg2=0)
How do I fix?

Basically more than half the src/opengl/*.cpp &*.h have this issue.

Any fix should be compatible with GCC.

I have cloned Gem from github repo and have created a new branch (osx_10.9_x64) to comit my efforts.

Thanks!
