Type overloading macro

I have a bunch of printf debug helper macros and it would be pretty cool to have to not specify the type, is there anything you can do to allow something like macro overloading in c(can be gcc specific if its available in gcc 4.3). I thought maybe typeof but apparently that doesn't work.

example macro(I also have some ascii terminal color stuff that I can't remember of the top of my head)

#ifdef _DEBUG
#define DPRINT_INT(x) printf("int %s is equal to %i at line %i",#x,x,__LINE__);
.
.
.
#else
#define DPRINT_INT(x)
.
.
.
#endif
