The naive version of this often breaks because the shell does
funny things to the quotes, especially when the makefile uses a shell
script to call the compiler.

-include somefile.h 

and putting it in there works however.

Still this is a semantics change to older compilers, because it implicitely
forces -Werror -Winline

There are some functions that are not inlined for legitimate reasons and
these error out now.
