@gilles-peskine-arm - We already have an open task in JIRA (IOTSSL-1042) to update the mingw documentation.

Review comments from @gilles-peskine-arm addressed. Please review my responses and respond or approve. Thanks!

Updated with a comment on the codepage`CP_ACP`. @gilles-peskine-arm / @Patater - please re-review and approve.

@Patater - You're right. It was a regression introduced by the PR, which is now fixed. The PR is [now passing the Windows CI](https://jenkins-internal.mbed.com/job/mbedtls-release/282/console) and builds for Win32 and x64...

The problems in b862f4c were introduced when I rebased the original PR against the current `development` branch, and I inadvertently introduced `mbedtls.lib` into the project files which reverted a change...

I've rebased this PR, and kicked off a CI job on buildbot, and a release job on Jenkins. @Patater / @gilles-peskine-arm - Could you please re-review and approve this PR?...

retest

Failed Travis CI due to stale Visual Studio project files, found by `tests/scripts/check-generated-files.sh`. I'll refresh them and update the PR.

Fixed the stale project files and the merge error. Everything should now pass the CI.

@k-stachowiak / @Patater / @gilles-peskine-arm - I've fixed the style issue @k-stachowiak identified. Could you please re-review? Scheduled a Windows release job as build #552.
