# SYNOPSIS

#

#   AX_TRY_COMPILE_JAVA

#

# DESCRIPTION

#

#   AX_TRY_COMPILE_JAVA attempt to compile user given source.

#

#   *Warning*: its success or failure can depend on a proper setting of the

#   CLASSPATH env. variable.

#

#   Note: This is part of the set of autoconf M4 macros for Java programs.

#   It is VERY IMPORTANT that you download the whole set, some macros depend

#   on other. Unfortunately, the autoconf archive does not support the

#   concept of set of macros, so I had to break it for submission. The

#   general documentation, as well as the sample configure.in, is included

#   in the AX_PROG_JAVA macro.
