Subject: Include <stdlib.h>.
X-Git-Tag: v5.3.0~212

Include <stdlib.h>.
(__fpending): Abort if PENDING_OUTPUT_N_BYTES is negative.
This ensures that if there is an error in the definition of the
PENDING_OUTPUT_N_BYTES expression, we'll find about it right away;
this value is used only in the rare event that close_stdout's
fclose fails with EBADF.
