This should be fixed in newer versions of skeleton.c.

Once again, newer versions actually use a #include <stdlib.h> statement.
They also have a #ifdef __cplusplus areoung the getenv() prototype, which
is altogether unnecessary (the prototype, not the #ifdef, but that too, by
implication).
Have a look at bin/2792 for what I suspect is a better fix.
Cc: 'd to steve@freebsd.org, too, since he's listed in the Responsible:
field for bin/2792.
