Your header files seem to be broken.  The above error is generated
because it can't find the definition for uid_t which is available in
cygwin/types.h, which is included automatically by pwd.h through
including sys/type.h.  Somehow your header files are mixed up.
gcc -E might be helpful.  Do you have a fresh Cygwin install?
