dnl dnl @synopsis LLNL_PROG_JAVAH
dnl
dnl LLNL_PROG_JAVAH tests the availability of the javah header generator
dnl and looks for the jni.h header file. If available, JAVAH is set to
dnl the full path of javah.  Unlike Luc's implementation, this doesn't
dnl update CPPFLAGS.  Instead it defines JNI_INCLUDES.
