[11u] RFR: 8261089: [TESTBUG] native library of test TestCheckedReleaseCriticalArray.java fails to compile with gcc 4.x

[Jayashree Huttanagoudar]

Hi,

Could you please review this build fix for test-image on gcc 4.4.x
systems.  JDK-8258077 is included with 11.0.11+1 and has an initial
declaration in the for loop. The fix is minor and makes the build proceed
further.This breaks our vanilla OpenJDK 11 builds. This isn't really
suitable for jdk/jdk as   it's moved on to later toolchains. There is no
point in fixing this for later JDKs as those aren't going to be buildable
with those old compilers.

Bug: https://bugs.openjdk.java.net/browse/JDK-8261089

Proposed Fix:
diff --git
a/test/hotspot/jtreg/runtime/jni/checked/libTestCheckedReleaseCriticalArray.c
b/test/hotspot/jtreg/runtime/jni/checked/libTestCheckedReleaseCriticalArray.c

Testing: Build of test-image target progress with this fix.

Thoughts?
