Use compiler directive to include config.h as a first file
This is part of the conversion to modern buildchain. The compiler directive (-include
for gcc/clang) and (ForcedIncludeFiles
for MSVC) is used to make sure config.h
is always included as a first file.
Coccinelle was then used to remove #include <config.h>
from the source files.
