When we use CONFIG_PROFILE_ALL_BRANCHES, every 'if()' introduces a static variable, but that is not allowed in 'extern inline' functions: mpi-inline.h:116:204: warning: '______f' is static but declared in inline function 'mpihelp_sub' which is not static mpi-inline.h:113:184: warning: '______f' is static but declared in inline function 'mpihelp_sub' which is not static mpi-inline.h:70:184: warning: '______f' is static but declared in inline function 'mpihelp_add' which is not static mpi-inline.h:56:204: warning: '______f' is static but declared in inline function 'mpihelp_add_1' which is not static This changes the MPI code to use 'static inline' instead, to get rid of hundreds of warnings.
