The HP/UX cc compiler returns structure values from functions in the address pointed to by register a1, even for small structures. Gcc only does this for structures > 8 bytes. So it is impossible to call dbm routines. The following insertion in tm-hp9k320.h will correct this behaviour: /* pass all struct returns via memory */ #define RETURN_IN_MEMORY(type) \ (TREE_CODE (type) == RECORD_TYPE || TREE_CODE (type) == UNION_TYPE) (This is for gcc version 1.35) -- Piet van Oostrum, Dept of Computer Science, University of Utrecht Padualaan 14, P.O.
