Well, here is the script in configure.in that can check the JDK version:
#--------------------------------------------------------------------
# Test the JDK version
#--------------------------------------------------------------------
AC_MSG_CHECKING([the Java compiler with a simple compile])
JVERSION=unknown
if "$JAVAC" confTest.java ; then
AC_MSG_RESULT(ok)
AC_MSG_CHECKING([the value of the java.version Property ])
if "$JAVA" confTest > /dev/null; then
JVERSION=`"$JAVA" confTest`
AC_MSG_RESULT($JVERSION)
else
AC_MSG_ERROR(['"$JAVA" confTest failed.'])
fi
else
AC_MSG_ERROR(['"$JAVAC" confTest.java failed.'])
fi
AC_MSG_CHECKING([the JDK version])
UPGRADE_JVM=no
case "$JVERSION" in
1.1.*) UPGRADE_JVM=yes;;
1.2.*) UPGRADE_JVM=yes;;
1.3.*) UPGRADE_JVM=yes;;
1.4.*) AC_MSG_RESULT([Your JDK version is OK]);;
*) AC_MSG_RESULT([ok, you are running $JVERSION]);;
esac
if test "$UPGRADE_JVM" = "yes"; then
AC_MSG_ERROR([Please upgrade your JDK version])
fi
And the related java code:
public class confTest {
public static void main(String args[]) {
System.out.print(System.getProperty("java.version"));
}
}
Anyone knows how to test the gcc version in configure.in?

Does anyone know how I can modify the configure.in or Makefile.in file to
check the version of the gcc and java so that I can issue a warning when the
gcc or java version is not high enough?

gcc can be set to require that all functions be declared before use.
I think ANSI C requires this.
I don't have glpk.c in front of me,
so I can't be sure that that is the problem.
