Matthias Rechecked with 4.1.2. Bug submitter writes: 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. powerpc: $ gcc -dM -E -xc /dev/null | grep linux #define __linux 1 #define __linux__ 1 #define __gnu_linux__ 1 #define linux 1 $ gcc -std=c99 -dM -E -xc /dev/null | grep linux #define __linux__ 1 #define __gnu_linux__ 1 x86: $ gcc -dM -E -xc /dev/null | grep linux #define __linux 1 #define __linux__ 1 #define __gnu_linux__ 1 #define linux 1 $ gcc -std=c99 -dM -E -xc /dev/null | grep linux #define __linux 1 #define __linux__ 1 #define __gnu_linux__ 1 -- Summary: cpp: x86/powerpc inconsistency for the __linux macro Product: gcc Version: 4.1.2 Status: UNCONFIRMED Severity: normal Priority: P3 Component: preprocessor AssignedTo: unassigned at gcc dot gnu dot org ReportedBy: debian-gcc at lists dot debian dot org http://gcc.gnu.org/bugzilla/show_bug.cgi?id=28314
