I have done an update to svn, please try that first, if not....

I need your help for this because I can't reproduce.

the include/sys/{sendfile.h,cdefs.h}, 
libc/sysdeps/linux/common/{sendfile.c,syscalls.h} matter.

sendfile.c includes syscalls.h, that disables __USE_FILE_OFFSET64 if it is 
defined. after this it includes sys/sendfile.h that should catch the first 
prototype for sendfile()

could you please add #warning here-nr(nr=1....) or something else that you 
can identify what part you include from sendfile.h?

I assume that for some reason when you get to include sendfile.h, you have 
__USE_FILE_OFFSET64 defined, please find the place where it gets defined

Thanks, Peter
