`float' functions. The math functions now reside in a separate library,
so programs using them will need to use `-lm' their linking commands.
+* Ulrich Drepper has contributed support for an `/etc/nsswitch.conf'
+ mechanism similar to that found in Solaris 2. This is now used for the
+ group, passwd, hosts, networks, services, protocols, and rpc databases.
+ The `nsswitch.conf' file controls what services are used for each
+ individual database. This works by loading shared libraries with names
+ specified in `nsswitch.conf', so service modules can be changed or added at
+ any time without even relinking any program. A future release of the
+ separate NYS package will provide NIS/YP and NIS+ modules for this interface.
+
* The new functions `strtoq' and `strtouq' parse integer values from
strings, like `strtol' and `strtoul', but they return `long long int' and
`unsigned long long int' values, respectively (64-bit quantities).
