dnl @synopsis AC_CHECK_RQRD_CLASS
dnl
dnl AC_CHECK_RQRD_CLASS tests the existence of a given Java class, either in
dnl a jar or in a '.class' file and fails if it doesn't exist.
dnl Its success or failure can depend on a proper setting of the
dnl CLASSPATH env. variable.
dnl
dnl Note: This is part of the set of autoconf M4 macros for Java programs.
dnl It is VERY IMPORTANT that you download the whole set, some
dnl macros depend on other. Unfortunately, the autoconf archive does not
dnl support the concept of set of macros, so I had to break it for
dnl submission.
dnl The general documentation, as well as the sample configure.in, is
dnl included in the AC_PROG_JAVA macro.
