Bug: https://bugs.openjdk.java.net/browse/JDK-8224087
webrev: http://cr.openjdk.java.net/~dholmes/8224087/webrev/
The need to remove a for-loop declaration expression to appease gcc 4.8
annoyed me enough to investigate setting C99 as our minimum allow
C-language level when compiling. It turned out to be a lot more complex
a situation than I thought due to toolchain quirks. See lots of details
in the bug report.
To summarise the changes:
- gcc: force to -std=gnu99
- clang force to -std=gnu99
- Solaris studio - no effective change
- Visual Studio - no change
- xlc - no effective change (but we use the explicit flag rather than
accepting it as default)
I've checked how this works with all the toolchains except xlc as I have
no access to that. Some assistance from someone who can verify the
correctness on xlc would be appreciated.
Thanks,
David
