I've compiled that code:
[code]
static __forceinline int f(void) { return 1; }
int main()
{
int i = f();
return 0;
}
[/code]
with gcc:
torri:~/code: ~/local/opt/mingw-w64-x86_32/bin/i686-w64-mingw32-gcc
-o forceinline forceinline.c
forceinline.c:1:22: error: expected ‘=’, ‘,’, ‘;’, ‘asm’ or
‘__attribute__’ before ‘int’
with Visual Studio 2008: no error, nor warning. Here is the output
(in french, sorry) :
