#3 Flexport timespec redefinition in win32

[Rich Mattes]

In Flexiport's timeout.h file, the timespec struct is defined, and annotated with a comment that there's no timespec on windows. When using flexiport with Player on windows, the windows version of the pthread.h file is included, resulting in a redefiniton error. It looks like pthread.h creates a define called HAVE_STRUCT_TIMESPEC, maybe flexiport could check for that before defining timespec.
