if this means that glibc's sysdeps subdir contains missing functions  for 
operating systems, yes

not only the header also the functions. windows compilers does have only a 
subset of the posix api, the win dir provides this functions. Currently there 
are about 60 functions. The problem is that KDE is currently very much unix 
related and on windows  things goes slighty other.  In the short it seems not 
be possible to wrap all platform depending low level functions with c++ 
classes, so adding this additional functions to KDE is the better way.

Yes, they located in the win dir.
