SFU port part2

[Steven Edwards]

ok got configure working but some of the porting definitions are hosed. 
When I try to build anything I get this:

../include/wine/port.h:49: Error: conflicting types for `mode_t'
/usr/include/sys/types.h:45: Error: previous declaration of `mode_t'
../include/wine/port.h:52: Warning: redefinition of `off_t'
/usr/include/sys/types.h:69: Warning: `off_t' previously declared here
../include/wine/port.h:55: Error: conflicting types for `pid_t'
/usr/include/sys/types.h:55: Error: previous declaration of `pid_t'
../include/wine/port.h:58: Warning: redefinition of `size_t'
/usr/include/sys/types.h:89: Warning: `size_t' previously declared here
../include/wine/port.h:61: Warning: redefinition of `ssize_t'
/usr/include/sys/types.h:94: Warning: `ssize_t' previously declared here

Any suggestions?
Thanks
Steven
