Subject: [Bug other/23656] New: Cross-compilation with newlib fails in libiberty
X-Bugzilla-Reason: CC
X-SW-Source: 2005-08/txt/msg03606.txt.bz2
List-Id: <gcc-bugs.sourceware.org>

While attempting to generate a cross-compiler, I got a build error in
libiberty/strsignal.c, because newlib has a strsignal() definition but libiberty
does not test for the strsignal() declaration in the newlib headers.
