#
# SYNOPSIS
#
# AX_PROG_JAVA_CC
#
# DESCRIPTION
#
# Finds the appropriate java compiler on your path. By preference the java
# compiler is gcj, then jikes then javac.
#
# The macro can take one argument specifying a space separated list of
# java compiler names.
#
# For example:
#
# AX_PROG_JAVA_CC(javac, gcj)
#
# The macro also sets the compiler options variable: JAVA_CC_OPTS to
# something sensible:
#
# - for GCJ it sets it to: @GCJ_OPTS@
# (if GCJ_OPTS is not yet defined then it is set to "-C")
#
# - no other compiler has applicable options yet
#
# Here's an example configure.in:
#
# AC_INIT(Makefile.in)
# AX_PROG_JAVA_CC()
# AC_OUTPUT(Makefile)
# dnl End.
#
# And here's the start of the Makefile.in:
#
# PROJECT_ROOT := @srcdir@
# # Tool definitions.
# JAVAC := @JAVA_CC@
# JAVAC_OPTS := @JAVA_CC_OPTS@
# JAR_TOOL := @jar_tool@
