Equivalences between flags (parameters) of the cc and gcc compilers

Hi. First of all, I appreciate your time spent on your response.

I need to compile an application and the makefile it provides uses the cc compiler and the parameters (flags) are not equivalent with my compiler. I have the gcc 4.6.1 compiler.

Could you help me identify what are the parameters (flags) to make the makefile work with gcc.

This is the line of the code:

CC = cc -q64 -qlanglvl=extc89 -qcpluscmt -qarch=com -qmaxmem=16384 -bmaxdata:0x80000000 -D_THREAD_SAFE -DCOBOL_64BIT
