I'm getting lots of warnings like so:
In file included from
..\..\tools\win\static_initializers\static_initializers.cc:5:
C:\b\depot_tools\win_toolchain\vs_files\95ddda401ec5678f15eeed01d2bee08fcbc5ee97\DIA
SDK\include\dia2.h(30,10): error: non-portable path to file '"Windows.h"';
specified path differs in case from file name on disk
[-Werror,-Wnonportable-include-path]
#include "windows.h"
^~~~~~~~~~~
"Windows.h"
dia2.h is a system include, and we include it in the search path via
-imsvc. Normally warnings aren't emitted for system headers. Do you know
why this is happening here?
