C99 strict aliasing rears it's ugly head again in the gtk+ codebase | 9 comments (9 topical, 0 hidden) | Trackback

I must wonder, by ksandstr (3.00 / 0) #1 Sun Apr 25, 2004 at 11:01:18 AM EST

What the main point is in making an existing body of C89 -style code into C99 code if GCC will continue to support C89 in its future revisions? It seems to me that the last bug you mention is directly due to the fact that the C89 code is written so that it complies with only the less strict aliasing rules, and that the eventual emergence of hacks like this at the seams where old meets new would be inevitable (in cast-heavy code anyway).

... and it's a query I have about how they are building GNOME and GTK+. Should the target be C89 or C99?

According to jdub on irc (nice guy, I went to school with him), he reckons the answer is "undefined" - such a great programming term for "we don't know", btw, or C89 if possible.

Is like doubly ensuring limited response.

I put it up for my own reference, as well as others. It's not about popularity! It's about... well... getting it out there.

Believe me after a day at work the last thing I'd want to do is even more coding.... :-)

I enjoy hacking, and the glory of recognition.
