Only those warnings. > >hristo After you email the assembly Cygnus of hash.c I came to the folowing conclusing: -all the line numbers which are warned are 2 kind of instructiongs: 1) xchgw %eax,lock_hasha 2) xchgw %eax,lock_hashb -xchgw is an instructing which expect an 16bit var. eax and lock_hashb are both 32-bit (lock_hasha for example is of type lock_t and lock_t is of type int, which is 4 byte on intel 32bit) so the instruction to be used has to be xchgl instead of xchgw. The compiler warns about this and said it will use ax instead of eax. This is not entirely correct since ax can only contain the least signigicant part of eax. So works only as long lock_hasha doesn't exceed the 65536. I don't have cygnus home here. So I can't try for myself. Maybe you can fix this kind of error with some kind of compiler patch and or compiler option. Kind regards, Michel Langeveld
