apply patch to gmon

["Gian Lorenzo Meocci" <glmeocci at gmail dot com>]

Hello,

I am patching gmon  for multithreading enviroment. So i need to use
pthread library
but i am having some troble with Makefile.

I always get output like this:

gcc   -shared -static-libgcc -Wl,-O1  -Wl,-z,defs

Could you please tell me where i can find some documentation about
GLIBC Makefile???
Or, better, how can i fix this problem???

thanks,
