Hi, all,
My question is per the subject of this e-mail: why is C99 not enabled
by default in Objective-C projects? It seems more "modern," or at
least more "convenient," what with the ability to declare variables in
for-loops and whatnot. I've seen list postings that say that it's
"fine" or "okay" to use C99 in Cocoa projects, without conflicts --
but *why* is never answered, from what I can tell.
One of the documentation files has the following:
Imagine that you are working on a C program under Xcode. During
development, you learn that the program must be portable to systems
that support only pre-C99 language compliance, both GNU and non-GNU
compilers. As a result, your code cannot contain C99-specific
language features.
Because the default standard tool build uses the GNU89 language
dialect, you are confident that your code will work well under these
compilers. Unfortunately, this is not the case. For example, imagine
your code base contains variable-length automatic arrays, as shown
in Listing 3.
So I might infer that the lack of default C99 compliance is for
compatible, multi-platform C code. Is that the case?
Cheers,
Andrew
