I'm running a current NetBSD build from the Alpha related sources supped about a week ago on my 433MHz-PC164. I have rebuilt/updated libstdc++ with the following
file that Todd Vierling fixed ( I really thank him)

  -rw-rw-r--  1 root  wheel  6442 Feb  2 21:09 /usr/src/gnu/dist/libio/iopopen.c

in the /usr/src/gnu/dist/libio/ directory.
However, when I compile a simple program using iostream, e.x., a "hello world" program, the following warning is still occured.

	>g++ -o hello hello.cc
	/usr/lib/libstdc++.so: warning: reference to compatibility vfork();
	include <unistd.h> for correct reference


The version of the current compiler is the following.

	>g++ -v
	Using builtin specs.
	gcc version egcs-2.91.60 19981201 (egcs-1.1.1 release)

Does nobody notice the same warning?
