JDK-8132379 - -J options can cause crash or "Warning: app args parsing error passing arguments as-is"
Description
Change '8132379: -J options can cause crash or "Warning: app args parsing error passing arguments as-is"' uses the following non ANSI C compatible code for declaring a block-level variable:

    for (i = 0; i < argc; i++) {
        j = appArgIdx[i];
        jboolean arg_expand = (JLI_StrCmp(stdargs[j].arg, strv[i]) == 0)
                                ? stdargs[j].has_wildcard
                                : JNI_FALSE;
But ANSI C only allows the declaration of block local variable at the beginning of a block.

As the fix is trivial, it makes no sense to restrict ourselves to compilers which support this C99 feature (like VS2013).
