Subject: Cannot compile mandrake 8.2 Kernel

The stupid mandrake 8.2 kernel (2.4.18-mdk6) won't compile.  I know,
mandrake is kind of a newbie distro, but I needed to mess with that kernel
for some reason (don't ask).

Anyway it gets errors like the following then you do make modules.  I
notices someone else also had the exact same problem.. also below is
preprocessor output from that compile... I think the problem is due to
some of the exported kernel symbols containing parens...:

Here is the cpp output.. this is an except of the first thing the above
barfed on:


# 33 "/usr/src/linux-2.4.18-6mdk-rtl/include/asm/processor.h"
struct cpuinfo_x86 {
        __u8 x86;
        __u8 x86_vendor;
        __u8 x86_model;
        __u8 x86_mask;
        char wp_works_ok;
        char hlt_works_ok;
        char hard_math;
        char rfu;
    int cpuid_level;
        __u32 x86_capability[4];
        char x86_vendor_id[16];
        char x86_model_id[64];
        int x86_cache_size;

        int fdiv_bug;
        int f00f_bug;
        int coma_bug;
        unsigned long loops_per_jiffy_R_ver_str(ba497f13);
        unsigned long *pgd_quick;
        unsigned long *pmd_quick;
        unsigned long *pte_quick;
        unsigned long pgtable_cache_sz;
} __attribute__((__aligned__((1 << ((5))))));

I think the problem is that unsigned long
loops_per_jiffy_R_ver_str(ba497f13); struct member .. I dunno why
loops_per_jiffy got renamed to that mangled kernel symbol name.. but I
suspect it has to do with buggy header files. (I noticed loops_per_jiffy
was #defined to something else).


At any rate.. has anyone else encountered this problem with that mandrake
kernel?  If so how did you fix this?
