RE: autoconf enhancement for Interix

[Jerker Bäck]

Hello Martin,

> #define _ALL_SOURCE 1 to enable all functions in the system headers.
Are you sure this is wise?

I never understood why anyone would not have all functions available
(_ALL_SOURCE not defined), but the possibility is there for some reasons. So
accordingly, c89 do not define _ALL_SOURCE and use strict ANSI-C. cc on the
other hand define _ALL_SOURCE and use C extensions. I assume you use Interix
gcc, right? So, this concerns Interix gcc only and maybe the patch should
test for GNU extensions before define _ALL_SOURCE.

Cheers
