How about something like this as a starting point...
In a common file such as asterisk.h:
#define AST_CVSID(x) \
static const char cvsid = x; \
static void __attribute__((constructor)) initcvsid(void) \
#define AST_CVSID(x) static const char cvsid = x;
And then in each .c file you could have:
#include "asterisk.h" /* if not already included */
And finally implement ast_register_cvsid(const char *cvsid) to collect up
all the strings and make them available via a CLI command.
Using GCC file-scope constructors allows the ids to be registered
without needing explicit init calls for each file.
Using another compiler (how commonly is that done?) would still define
the strings for use with the "ident" command, even if it couldn't
register them for a CLI command.
Not sure what to do about the .h files....
