could you please have a look, why this change: [1] broke jpeg-turbo 
compilation on MSVC 14.0.

For the record, MS did a great job in splitting the include path in two

* compiler internal
* UCRT (Universal C Runtime)

This is mapped in configure.ac: [2] and respected in external modules.
When you overwrite CFLAGS in the invocation of gcc-warpper, then
presumably the UCRT include path is lost.

Here is the config.log with offended commit: [3]. And this one after
I've reverted it: [4], you see the include, it worked in the end.
This solved the breakage, caused by: [1].
