The sybdb.h header is included only by the C file that does the dblib 
stuff right?  so foo.c gets run through the preprocessor and becomes an 
intermmediate form with all #include's and #define's and such resolved so 
after cpp is done with it you have dbopen() being tdsdbopen() which gets 
compiled and linked against the rest of the libraries including dbm and 
libsybdb your call to dbopen() actually becomes a call to tdsdbopen() in 
libsybdb.a and dbm's call to dbopen stays untransformed and goes to dbopen 
in libdbm.a (or whatever the name of the library is).
