Without knowing about things like QEMU_PLUGIN_EXPORT it chokes trying to understand the code. Evidently this is a problem for the kernel as well as the long stream of regex substitutions we add to in this patch can attest. Fortunately we have a fairly common format for all our compiler shenanigans as applied to functions so lets just filter them all out.

charset=UTF-8 Content-Transfer-Encoding: 8bit Mingw recognizes that "0x" has value 0 without setting errno, but fails to advance endptr to the trailing garbage 'x'. This in turn showed up in our recent testsuite additions for qemu_strtosz (commit 1657ba44b4 utils: Enhance testsuite for do_strtosz()); adjust our remaining tests to show that we now work around this windows bug. This patch intentionally fails check-syntax for use of strtol.
