    Subjectupdated gcc-3.4.0 fixes patch for 2.4.27-rc3
    There's now an updated gcc-3.4.0 fixes patch for 2.4.27-rc3 at

    This update includes two cleanups:

    1. The fix for the __attribute__((packed)) problem in ftape-bsm.h
    has been corrected. The problem is that

    typedef struct { char c[3]; } Name __attribute__((packed));

    generates gcc warnings about the 'packed' attribute being
    ignored. I assumed this was because packed is meaningless
    on a struct containing only char values, so the previous
    patches simply removed the attribute. However, the problem
    turns out to be syntactic: __attribute__((packed)) is only
    allowed in struct/union declarations, not in typedef:s.
    The revised patch moves the attribute into the struct part:

    typedef struct { char c[3]; } __attribute__((packed)) Name;

    2. The patches that removed 'inline' from function declarations
    have been removed. The problem is that include/linux/compiler.h
    defines inline as follows:

    #if __GNUC__ == 3
    #if __GNUC_MINOR__ >= 1
    # define inline __inline__ __attribute__((always_inline))

    A number of functions are marked inline and then called in
    contexts where their function bodies aren't visible. gcc-3.4.0
    takes the always_inline attribute literally, and terminates
    with an error in these cases.

    The previous patches removed the problematic inline annotations.
    The proper fix is to eliminate the always_inline attribute:

    #if __GNUC__ == 3
    #if __GNUC_MINOR__ >= 1 && __GNUC_MINOR__ < 4
    # define inline __inline__ __attribute__((always_inline))

    This is what the 2.6 kernels do, and my patch set already included
    this change. So the inline removals were unnecessary and have been

    Both cleanups are due to Marcelo questioning me about the validity
    of the previous versions of these fixes.
