#3405: boost/interprocess is incompatible to Win9x

Comment(by anonymous):

 not very cool. sorry.

 To make boost/interprocess/sync/*_lock.hpp useable under Win98 you not
 only need to wrap get_file_size and set_file_pointer_ex - you also must
 overcome a strange assumption set_file_pointer_ex does...
 It assumes that if you point the file-pointer over the actual size of the
 file and call SetEndOfFile afterwards, the file not only increases (what
 is true and documented) - the remaining bytes are initialized by zero.
 I cant find that this is documented - the documentation for
 SetFilePointerEx says "leaving the intervening bytes uninitialized" ...
 but it seems to work under XP ...
 I would call this a bug...
 but maybe its not the beauty that counts anyway...

 (sorry, but after crawling this part of the boost-code i lost some respect
 points for the project...)
