Bug ID: 211818
Summary: contrib/ntp/ntpdc/ntpdc.h redefines machine/frame.h's
MOREARGS macro (TARGET_ARCH=powerpc example)
Product: Base System
Version: 11.0-STABLE
Hardware: ppc
OS: Any
Status: New
Severity: Affects Only Me
Priority: ---
Component: bin

machine/frame.h for powerpc seems to have chosen a name (MOREARGS) that is not
that unlikely for having conflicts with other code: a form of name space
pollution.

I noticed the warnings while cross compiling buildworld for TARGET_ARCH=powerpc
via the system clang 3.8.0 . (Not that the result respects the FreeBSD powerpc
ABI requirements for stack pointer handling: the generated code requires a
so-called red-zone. It has other problems as well.)
