Bug#265498: gcc-3.3: does not define macros like __i386__ or __ELF__ anymore
Package: gcc-3.3
Version: 1:3.3.4-7
Severity: normal
Hi
In earlier releases (sorry, I do not have the information
available when that was -- a few weeks ago?), the compiler
defined macros like __i386__ or __ELF__ which could be used in
the source with
#ifdef __i386__
// blah
#endif
The current release does not produce these symbols anymore
(sorry for the german locale):
$ /usr/bin/g++ -v -c -o file.cc

As you can see, it has this long list of defines which are missing in the
current Debian release of unstable.
