waitpid in C++ mode

[Bruno Haible]

On HP-UX 11.11 I'm seeing this link failure:

g++      -o test-sys_wait-c++ test-sys_wait-c++.o ../gllib/libgnu.a 
/usr/ccs/bin/ld: Invalid symbol type for plabel (test-sys_wait-c++.o, waitpid).
collect2: ld returned 1 exit status
*** Error exit code 1

It's caused by the extern "C" { ... } group that changes the name mangling of
the variable '_ZN6gnulib7waitpidE' to 'waitpid', leading to a collision with
waitpid from libc. The mistake dates back to 2010-09-29.

This fixes it:

        waitpid: Fix link error in C++ mode.
        * lib/sys_wait.in.h: Remove extern "C" { ... } group.
