Note: So far I've only been able to reproduce the failure on Amazon Linux 2, but the analysis of the causes is independent of platform:

Building JDK with this configuration: `--with-jtreg=/wf/tools/jtreg-7.5.1/ --with-boot-jdk=/wf/tools/jdk-23+37/ --with-debug-level=release` is failing with this error message:

* For target hotspot_variant-server_libjvm_objs_bytecodeTracer.o:

cc1plus: all warnings being treated as errors

The error is because of a combination of factors. `TraceBytecodesAt` is a develop flag which is being used here in the BytecodeTransfer::trace_interpreter method, which although is only used inside a NOT_PRODUCT block, isn't defined/declared inside a NOT_PRODUCT block. The problem only started showing up recently because (https://bugs.openjdk.org/browse/JDK-8350642) changed the type of `TraceBytecodesAt` from SIGNED int to UNsigned int.
