Hi Mateusz,

Oops. I checked everything, also using GCC, and didn't get this at my 
place, sorry.  Using gcc 4.3.0

It solves the warning from MSVC that hypot had to be _hypot.
1>c:\svn\geolib\trunk\src\cpp\library\gl\boost\ggl/projections/proj/tpeqd.hpp(89) 
: warning C4996: 'hypot': The POSIX name for this item is deprecated. 
Instead, use the ISO C++ conformant name: _hypot. See online help for 
details.
1>        C:\Program Files\Microsoft Visual Studio 
8\VC\include\math.h(455) : see declaration of 'hypot'

Maybe we need a headerfile or so.

I've changed it back. Just checked (got another compilation error in 
transform :-) , OK already solved).

Regards, Barend
