Author: metze

New Revision: 18895

WebSVN: http://websvn.samba.org/cgi-bin/viewcvs.cgi?view=rev&root=samba&rev=18895

Log:
AIX need to call pidl with --uint-enums as the compiler doesn't
like negative values in the generated code.

I'm not sure how we can solve that in samba3 as the generated code is commited

Maybe we need to alsways pass --uint-enums
