Re: [Tinycc-devel] static const not recognized as const value?

[Aharon Robbins]

Hi.

The answer is that this feature is not in C.  It is in C++, which
may be why you think it ought to work.  :-)

I too am amazed by tcc's speed. When I use it to compile gawk, though,
three of my tests, all related to wide characters, fail. I haven't
time to investigate why, though.

HTH,

Arnold
