Bug ID: 118725
Summary: libcpp build failure with NLS enabled
Product: gcc
Version: 14.2.0
Status: UNCONFIRMED
Severity: normal
Priority: P3
Component: other
Assignee: unassigned at gcc dot gnu.org
Reporter: judge.packham at gmail dot com
Target Milestone: ---
We have a crosstool-ng config
(x86_64-w64-mingw32,arm-cortexa9_neon-linux-gnueabihf) that enables NLS
support. When we get to building libcpp we hit the following build failure

I think libcpp's configure is missing a check for setlocale so it ends up
defining a fallback setlocale macro that confuses things when it sees the
definition in libintl.h.
