RFR [XS]: 8240603: Windows 32bit compile error after 8238676

[Baesken, Matthias]

Hello ,  please look into the following small change .
We noticed that the Windows 32 bit builds fail  now  in jdk/jdk .

Error :
libatExit.c(107): error C2373: 'JNI_OnLoad': redefinition; different type modifiers
d:\output-jdk-dev\support\modules_include\java.base\jni.h(1970): note: see declaration of 'JNI_OnLoad'

Looks like the recent change  "8238676: jni crashes on accessing it from process exit hook"
caused this; we need on Windows 32 bit

JNIEXPORT jint JNICALL
JNI_OnLoad(JavaVM *jvm, void *reserved) {  ... }


to avoid this .

Thanks, Matthias
