Why?
https://stackoverflow.com/questions/25311011/how-does-include-bits-stdc-h-work-in-c
And look at what is inside of this file:
https://gcc.gnu.org/onlinedocs/gcc-4.8.0/libstdc++/api/a01541_source.html
Are you realy need all of that?
This is unnecessary garbage that slows down the build of the program.
Also it is not a part of C++ standard, but GCC/MinGW specific thing and the reason why project can't be compiled in other compilers like MSVC, what is important.
