+# SYNOPSIS
+#
+# AX_JNI_INCLUDE_DIR
+#
+# 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:
+#
+# AX_JNI_INCLUDE_DIR
+#
+# for JNI_INCLUDE_DIR in $JNI_INCLUDE_DIRS
+# do
+# CPPFLAGS="$CPPFLAGS -I$JNI_INCLUDE_DIR"
+# done
+#
+# 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
+#
+# 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.

+# SYNOPSIS
+#
+# AX_PROG_CC_FOR_BUILD
+#
+# DESCRIPTION
+#
+# This macro searches for a C compiler that generates native executables,
+# that is a C compiler that surely is not a cross-compiler. This can be
+# useful if you have to generate source code at compile-time like for
+# example GCC does.
+#
+# The macro sets the CC_FOR_BUILD and CPP_FOR_BUILD macros to anything
+# needed to compile or link (CC_FOR_BUILD) and preprocess (CPP_FOR_BUILD).
+# The value of these variables can be overridden by the user by specifying
+# a compiler with an environment variable (like you do for standard CC).
+#
+# It also sets BUILD_EXEEXT and BUILD_OBJEXT to the executable and object
+# file extensions for the build platform, and GCC_FOR_BUILD to `yes' if
+# the compiler we found is GCC. All these variables but GCC_FOR_BUILD are
+# substituted in the Makefile.
