Thanks, I installed this as well (in coreutils and gnulib).

* m4/unlink-busy.m4 (gl_FUNC_UNLINK_BUSY_TEXT): Use prototype
to define main with arguments, for C++. Reported by Eric Blake.
* m4/c-stack.m4 (AC_SYS_XSI_STACK_OVERFLOW_HEURISTIC):
Prefer 'int main ()' to 'int main (void)', for C++.
* m4/getcwd-path-max.m4 (gl_FUNC_GETCWD_PATH_MAX): Likewise.
* m4/fsusage.m4 (gl_FILE_SYSTEM_USAGE): Specify a return type
for 'main', for C99 and C++.
