After this patch in glibc
http://sourceware.org/git/?p=glibc.git;a=commitdiff;h=dbb0472f054a4241feec09af30db850dd4d18a7b
it is necessary to define _GNU_SOURCE to ensure that wcpcpy and wcpncpy are
declared.
2011-04-01 Bruno Haible <address@hidden>
wcpcpy, wcpncpy: Ensure declaration on glibc >= 2.13 systems.
* m4/wcpcpy.m4 (gl_FUNC_WCPCPY): Require AC_USE_SYSTEM_EXTENSIONS.
* m4/wcpncpy.m4 (gl_FUNC_WCPNCPY): Likewise.
* modules/wcpcpy (Depends-on): Add extensions.
* modules/wcpncpy (Depends-on): Likewise.
* doc/posix-functions/wcpcpy.texi: Mention missing declaration on glibc
systems.
* doc/posix-functions/wcpncpy.texi: Likewise.
* doc/posix-functions/wcwidth.texi: Likewise.
