Hi Erik,
I can confirm the changes resolve the issues I was having. I looked at
the changes, but don't really have the background to comment on them.
thanks,
Chris

Hello,
When cross compiling, we compile a subset of the jdk for the build
host to be able to run jmod and jlink. Configure sets up a toolchain
for this through variables prefixed "BUILD_" (BUILD_CC etc). The new
nifty macro we have for conditionally setting compiler flags depending
on the version of the compiler is currently unaware of this. The
result is that if the compiler version for the target and build
toolchain differ, the macro will provide the wrong compiler flags.
This patch makes the version check macro able to handle both the
target and build toolchain. It also fixes the
BUILD_CC_DISABLE_WARNING_PREFIX variable which is currently always
empty. The result is that our cross compile configurations at Oracle
no longer emits warnings from the build toolchain.
