<pre>__has_include(<FILENAME>) may change the FILENAME (by adding spaces) if it
includes certain symbols. It will change meaning of the program. Small example:
<span class="quote">> cat has_inc.cpp </span >
#if __has_include(<test/c++config.h>)
#endif
<span class="quote">> clang-format has_inc.cpp </span >
#if __has_include(<test / c++ config.h>)
#endif
