This probably results from having previously used it in another file
without declaring the return type in that file. This causes an
implicit declaration of function-returning-int.
The proper fix would probably be to only use the declarations from the
header files. Using the return value from sprintf is a bad idea at
this time, however. Currently, the return value (actually, the return
*type*) varies between different types of UNIX systems. The BSD
version is changing in the 4.3BSD-tahoe release to conform to the
pANS-C description, and will return an int.
