Where is the build setting for C99?

Question

How do I change the build settings in my objective-C Cocoa project so that the compiler uses C99?
In particular, I want to be able to write
for (int i = 1; i < 100; ++i)
instead of
int i;
for (i = 1; i < 100; ++i)
And I want to be able to write
UInt64 myBigUnsigned = (1 << 63);
And I want to do lots of bitwise operations on UInt64 variables.
Also, are there any issues I should worry about doing these things?

James,

Look at the C language Dialect setting in the Project Build settings. "Project" menu, -gt; "Edit Project Settings", then choose the "Build" tab. It's in the "Language" collection. There's a pop-up there and one of the choices is "C99".
Sorry I can't be much help on the rest.
best,
