To clarify:
-I use CPPFLAGS (be careful not to override user supplied one)
-L,-R use LDFLAGS (be careful not to override user supplied one)
The LIBS variable is used to list additional libraries to use during
linking, such as "-lfoo -lbar." Use CFLAGS for compiler flags
(e.g. -g, -O2, etc).

Here's a more compact form:
AC_SEARCH_LIBS(gethostbyname, nsl [,action-if-stuff, ,])
