Hotspot(1.4.2) should follow ISO C{89,99} and C++98

A licensee find out the hotspot source code does not follow ISO.

They tried to build JDK source code(1.4.2_05) in RedHat Enterprise Linux 4.0(64bits)
with gcc/g++ 3.4.2 and 3.4.1, there occurred some compile errors.

According to licensee's investigation, errors occurs in the lines which includes
"##" in pre-processing.
Specifically speaking, for example, methodName##signature in the following "(*)HERE" line.

---- src/share/vm/runtime/jvmdiInterfaceSupport.hpp ---
....
#define __JVMDI_ENTER(TransitionClass, trace, result_type, methodName, signature) \
extern "C" { \
  result_type JNICALL methodName signature { \
    JavaThread* thread = (JavaThread*) ThreadLocalStorage::thread(); \
    TransitionClass __tiv(thread); \
    __ENTRY(result_type, methodName##signature, thread) \ <==(*) HERE
    debug_only(VMNativeEntryWrapper __vew;) \
    debug_only(const char* const _jvmdi_methodName_ = #methodName;) \
    debug_only(bool _trace_ = trace; ); \
    debug_only(if (TraceJVMDICalls && _trace_) { JvmdiTraceWrapper _ignore(#methodName); });

#define JVMDI_ENTER(result_type, methodName, signature) \
  __JVMDI_ENTER(ThreadInVMfromNative, true, result_type, methodName, signature)
