The new xcode 2.2's gcc 4.0.1 compiler update has apparently
dropped support for nested functions. Apple's release notes for
gcc do not even mention this change... :(
They were in the online read-me file:
Nested Function support: We are deprecating nested functions (a gcc
extension
to C) in this release. For now, nested functions will cause a
warning.
Before I downgrade to gcc 4.0, is there a command line option to re-
enable nested functions?
I don't think so. But the project should still build, unless you
activated treating warnings as errors.
Why were they disabled?
Because they were a GCC extension, and the GCC developers have been
trying to make GCC more compliant with standards. That means
deprecating GCC extensions to the supported languages.
