@majorheading Synopsis

@smallexample
AX_JNI_INCLUDE_DIR
@end smallexample

@majorheading Description

AX_JNI_INCLUDE_DIR finds include directories needed for compiling
programs using the JNI interface.

JNI include directories are usually in the Java distribution. This is
deduced from the value of $JAVA_HOME, $JAVAC, or the path to "javac", in
that order. When this macro completes, a list of directories is left in
the variable JNI_INCLUDE_DIRS.

Example usage follows:

@smallexample
  AX_JNI_INCLUDE_DIR
@end smallexample

@smallexample
  for JNI_INCLUDE_DIR in $JNI_INCLUDE_DIRS
  do
          CPPFLAGS="$CPPFLAGS -I$JNI_INCLUDE_DIR"
  done
@end smallexample

If you want to force a specific compiler:

- at the configure.in level, set JAVAC=yourcompiler before calling
AX_JNI_INCLUDE_DIR

- at the configure level, setenv JAVAC

This macro depends on AC_CANONICAL_HOST which requires that config.guess
and config.sub be distributed along with the source code.  See autoconf
manual for details.

Note: This macro can work with the autoconf M4 macros for Java programs.
This particular macro is not part of the original set of macros.
