Hi Devs, I figured I'd better change the Subject: so you actually notice that we're talking about bumping the C language standard level for SANE to ISO C99. Until now, sane-backends code was supposed to be ANSI C (C89), which, for all intents and purposes, is the same as ISO C90.
Below, I suggest compiling a list of pros and cons and invite the SANE developers to support or object to the change.
