I have a patch but I can only submit it to GCC for legal reasons.

The following types I don't have a fix for yet:
__sanitizer_shmid_ds
__sanitizer___kernel_fd_set
__sanitizer_sigset_t/__sanitizer_kernel_sigset_t

__sanitizer_kernel_sigaction_t


Really I think sanitizer should be auto-generating this header rather than
having its own copy.

Actually I am not going to work on this mess.  That is what libsanitizer when
it comes to system calls.

People keep mentioning this but Asan team never seemed to bother.  Actually
missing symbols is not the biggest problems because they at least manifest
themselves at build time.  Have a look at bunch of lovely magic constants with
interspersing ifdefs all over the place in sanitizer_platform_limits_posix.h. 
Debugging type mismatch issues at runtime is so fun.
