using same macro arg as both: var and "var"?

["fkater@xxxxxxxxxxxxxx" <fkater@xxxxxxxxxxxxxx>]

Hi all,

I would like to define a macro with a single arg which
shall be used in both ways: The quoted and unquoted way:

#define macro1(a) void func##a(){ printf(a); }

Either way, of course, I get an error:

macro1(x);	  /* error: 'x' in printf not quoted */
macro1("x")	  /* error: func"x" not a func name */;


Instead I use a workaround with two args

#define macro2(a,b) void func##a(){ printf(b); }

However, the usage is not convincing:

macro2(x,"x");
macro2(a_long_name,"a_long_name");
...
