How about:

#define STRINGIT(x) #x
#ifdef SIGHUP
signame[SIGHUP] = STRINGIT(SIGHUP);
#endif

You might also be able to create a psuedo-array with the token pasting
operator as in:

#define SIG1 HUP
#define SIG2 INT
#define SIG3 QUIT
...
#define SIG(x) SIG ## x
signame[1] = STRINGIT(SIG(1));

Play with that to see if it works.

You might have to replace the enum with the list of #defines.
