[M3devel] quake c_source, gcc -I directive

[Jay K]

We should support something like
CFLAGS = CFLAGS & " -I/whatever" 
but we don't currently. ? 
SYSTEM_CC = SYSTEM_CC & " -I/whatever"almost works, but I don't believe generally does.
 - in the past, because SYSTEM_CC was readonly
 - currently because SYSTEM_CC is in some systems dynamically determined if/when any C code needs
   to be via configure_c_compiler (see cm3cfg.common) 
I don't know if Quake works this, way, but it'd be nice to be able to this: 
if defined(configure_c_compiler)
  previous_configure_c_compiler = configure_c_compiler
else
  proc previous_configure_c_compiler() is end
endproc configure_c_compiler() is
  previous_configure_c_compiler()
  SYSTEM_CC = SYSTEM_CC & " -I/whatever
end 
more generally though, this should be somehow abstracted per-platform like SYSTEM_LIBS? 
Granted, it is kind of the same for all C compilers, the -I switch.
The idea of a mult-dimensional abstraction per-library/include per-target per-host per-compiler (cc vs. gcc)
is kind of annoying, esp. given that -I is pretty universial. 
I feel like I'm missing something though.
We did have something like "CFLAGS".
But I don't see it currently..I'm not looking in a smart way..maybe more later....maybe...
