RE: [Help-glpk] Cannot compile glpk.c on Redhat 7.2 but will compileonRedhat 9.

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.
