jfh@rpp386.cactus.org (John F Haugh II) (05/20/91)
The kit I posted last week was missing the id.c file. This patch
includes the id.c file and the change to the Makefile to include
it in the list of files to wrap.

+ * id
+ * Synopsis:
+ * Print the current process identifiers. This includes the
+ * UID, GID, effective-UID and effective-GID.
+ *
+ * Notes:
+ * Straightforward implementation. Get the IDs and print
+ * them out. This is being included as a means of exercising
+ * the low level user database routines.
