Bug#345587: cpp-4.0: x86/powerpc inconsistency for the __linux macro
Package: cpp-4.0
Version: 4.0.2-5
Severity: normal
As shown below, the __linux macro is no longer defined when using
the C99 mode on a PowerPC machine. An x86 machine does not have
this behavior. This is normal for the linux macro to be no longer
defined (as it is not reserved), but I do not see why it should
be the case for the __linux macro. So, IMHO, the PPC should do
the same as x86.
On an x86 machine:
