cyberjupiter:
Like this ???#define NAME1 VALUE
#define VALUE NAME2
Which defines NAME1 to an empty string, THEN defines VALUE to "NAME2". Order of the #defines is important. Unlike c variable assignments, changing the definition of VALUE does NOT update any previous #defines that referenced it.
One could also reasonably ask why on earth anyone would WANT to create two #defines for the same value, other than as an entry to an obfuscated code contest...
