One way:  Have a definition file that builds a header file
with the typedef and a C file with the array.  I have used
this method successfully for things like symbol table string
constants and error messages.

Example:

file foo.def
------------
CMD:	A B C D
TOKENS:	Q X Y

generates foo.h:
----------------
typedef enum { A, B, C, D } CMD;
typedef enum { Q, X, Y } TOKENS;

and foo.c:
----------
char CMD_ltrs[] = { 'A', 'B', 'C', 'D' };
char TOKENS_ltrs[] = { 'Q', 'X', 'Y' };

Awk and Perl are good languages for building tools like this.
