This is an issue we ran into compiling 8u with VS2017:

https://bugs.openjdk.java.net/browse/JDK-8205677

We probably never noticed in JDK 12 because we don't do 32-bits builds 
with VS2017.

I just tried --disable-warnings-as-errors, and JDK 11 64bits as a

If you are running into warnings treated as errors, please try
configuring with --disable-warnings-as-errors. That is often
needed on
less tested platforms.

Note that as long as you run the build on a 64 bit system, you
can use a
64 bit bootjdk to build a 32 bit JDK.

Re: RFR: 8214796: Create a jlink plugin for stripping debug info symbols from native libraries

Renaming it to make it clear is good.  How about:

--strip-debug-attribute
--strip-native-debug-symbols

--strip-debug will invoke both --strip-debug-attribute and
--strip-native-debug-symbols, if supported.

Typically we want to strip both.  If only stripping debug attribute,
then it can use --strip-debug-attribute.

What do you think?
This make sense and I'm just wondering if we need to extend this to 
debug symbols that are in external files. This suggests exploring 
whether it should imply --exclude-files too.

Hmm... I thought it allows optional arguments. LegalNoticeFilePlugin
accepts an optional argument.
I don't think --dedup-legal-notices works without an option. It would be 
generally useful to allow optional values.
