8324184: Windows VS2010 build failed with "error C2275: 'int64_t'"

[gnu-andrew]

Hi all,

This pull request contains a backport of commit 4d078930 from the openjdk/jdk21u repository & the clean backport commit 4f80edf from 17u, also now in 11u. A new bug ID, JDK-8324184, had to be created as JDK-8317331, the original bug, is private.

The commit being backported was authored by Coleen Phillimore on 2 Oct 2023 and had no reviewers.

The backport fixes the VS2010 build which is broken by the placing of the declarations of low, high and index in JDK-8314295 after statements; see https://github.com/gnu-andrew/jdk8u-dev/actions/runs/7549766959/job/20554342418. This positioning is disallowed by C90.

Adding -Werror=declaration-after-statement to the build flags replicated the failure on GCC 8. I will look at adding this to the build in a follow-up fix. It also needs a number of other changes to fix Linux-specific code which has never been built to this standard.

Backport was clean and built fine on GNU/Linux with GCC 8.

Thanks!

/approval request Additional change from the January security update which fixes new code introduced by a security patch to compile on older C compilers that require declarations to precede statements in a block. Patch applies clean and fixes the Windows x86 (VS2010) build failure we are seeing in GHA.
