Not on my box with gcc-2.95.4. I have to admit that the specific circumstances 
are quite elaborate and most likely highly dependant on the compiler version, 
but '/usr/include/sys/types.h' includes 'bits/pthreadtypes.h' which defines 
the rw_lock structures at least on debian unstable with gcc-2.95.4 and 
libc6-dev-2.3.1-17.

what compiler and glibc version are you using?
