Yeah, it looks like Java finally decided to implement .NET's "IJW"[1].
Only about a hundred years too late. :(

These are the two usual places that declare the timespec struct:
/usr/include/time.h
/usr/include/linux/time.h
Unfortunately, they use different tags to see if timespec has already been
declared, so the conflict is probably coming from those. If you put this:
#define _LINUX_TIME_H
somewhere early in the source code, it should prevent the inclusion of
linux/time.h, which you probably don't want anyway.

Hmm. What is produced is just a set of interfaces with some constants. I
can't see anything that results in a call to native code. I'm not sure
if this is something I've done wrong, a limitation of the early release
or something else.
I tried using a different header file with (hopefully) more functionality:
/opt/java/openjdk-12-panama-b0/bin/jextract \
-I include \
-I /usr/lib/gcc/x86_64-linux-gnu/7.3.0/include \
-I /usr/include/linux \
-t org.openssl \
include/openssl/crypto.h
and I get:
/usr/include/linux/time.h:10:8: error: redefinition of 'timespec'
/usr/include/linux/time.h:10:8: error: redefinition of 'timespec'
It isn't immediately obvious to me where timespec is redefined - else
I'd tweak the relevant header file.

Thanks to some off-list help from Chuck, I have been able to make some
progress on this. The following:
/opt/java/openjdk-12-panama-b0/bin/jextract \
-I include \
-I /usr/lib/gcc/x86_64-linux-gnu/7.3.0/include \
-I /usr/include/linux \
include/openssl/rand.h
creates rand.h.jar
Next up is figuring out how to use this jar and testing how portable it is.

No joy. I suspect my lack of C knowledge is holding me back. I'm trying
this in an OpenSSL build directory:
/opt/java/openjdk-12-panama-b0/bin/jextract \
-I /usr/include/linux \
-I include \
include/openssl/rand.h
and getting
/usr/include/stdlib.h:97:8: error: unknown type name 'size_t'

This looks interesting. If I am reading the information correctly, it
could reduce the scope of Tomcat Native or even remove it completely
(assuming we dropped the APR connector).
I'm going to try experimenting with it and I'll report back.
