Can we have a check whether system headers produce warnings, something like this: $ cat headers.c #include <sys/types.h> #include <unistd.h> $ gcc -Wredundant-decls -c headers.c In file included from headers.c:2: /usr/include/unistd.h:100: warning: redundant redeclaration of 'lseek' /usr/include/sys/types.h:210: warning: previous declaration of 'lseek' was here /usr/include/unistd.h:139: warning: redundant redeclaration of 'ftruncate' /usr/include/sys/types.h:211: warning: previous declaration of 'ftruncate' was here /usr/include/unistd.h:164: warning: redundant redeclaration of 'truncate' /usr/include/sys/types.h:212: warning: previous declaration of 'truncate' was here > > Regards, > Andreas > > -- > SUSE LINUX Products GmbH, Maxfeldstr. 5, 90409 Nürnberg, Germany > GF: Jeff Hawn, Jennifer Guild, Felix Imendörffer; HRB 16746 AG Nürnberg
