No I’m not. ISO C99 tells us that those header are mandatory. I would not say that VC++ is ISO compliant. Fortunately, <iso646.h> contains on defines so it’s safe to add this include to make tcc a better ISO C99 as it claims to be.

Are you using the mingw-w64 runtime? We provide c99 support through an extra library. MS does not.

ISO/IEC 9899 :1999 (E) specifies that (Section 7.1.2 p. 165), Standard headers are:



























Those already in win32 lack

<complex.h> complex (and imaginary) support

<iso646.h>     restricted character set support via digraphs

<tgmath.h>  type-generic math macros


To make tcc a little bit more C99 conformant I added <iso646.h>


More includes are missing to support C11 but I’ll do nothing until we decide how C11 is going to be supported by tcc
