I've got a symple little patch to apply:
when including <linux/types.h> in a program and compiling with 'gcc
-ansi' gcc complains:
`In file included from test.c:1:
/usr/include/linux/types.h:162: error: parse error before "__le64"
/usr/include/linux/types.h:163: error: parse error before "__be64"`

These lines are:
typedef __u64 __bitwise __le64;
typedef __u64 __bitwise __be64;

__u64 isn't defined in include/asm-386/types.h when __STRICT_ANSI__ is
defined (as always when calling gcc -ansi):
#if defined(__GNUC__) && !defined(__STRICT_ANSI__)
typedef __signed__ long long __s64;
typedef unsigned long long __u64;
#endif

The following patch for linux-2.6.10-rc2 solves the problem:
(The patch wouldn't be needed for some 64Bit architectures, but i didn't
find an easy way of sorting these out)
