5# SYNOPSIS
6#
7#   AX_PROG_JAVAC_WORKS
8#
9# DESCRIPTION
10#
11#   Internal use ONLY.
12#
13#   Note: This is part of the set of autoconf M4 macros for Java programs.
14#   It is VERY IMPORTANT that you download the whole set, some macros depend
15#   on other. Unfortunately, the autoconf archive does not support the
16#   concept of set of macros, so I had to break it for submission. The
17#   general documentation, as well as the sample configure.in, is included
18#   in the AX_PROG_JAVA macro.
