The warning is harmless. On 3.x the #pragma gcc system_header disables
it.  Read more at GNATS database

in PR9601
[i386] -mrtd switch/stdcall attribute raises warnings for __builtin functions 


The __cdecl attribute in headers cause the warning when used with -mrtd.  If
the __cdecl qualifiers were not in headers, you would have even bigger problems
with -mrtd, since the libarary functions would be treated as stdcall as well.
