Patch: tfformat.c doesn't compile under hpux 10.20

[John David Anglin]

This patch fixes a problem compiling the test program tfformat.c under
hpux 10.20.  The include of stdlib.h has been removed because under hpux
it results in the inclusion of stdio.h.  The definitions in stdio.h
conflict with those in iostdio.h.

The header stdlib.h was included for `exit'.  The single use of exit in
the program has been changed to a return.  Tested under hpux and i686
linux.

	* tfformat.c: Don't include stdlib.h.  Use return rather than exit.
