pb to build kdelibs

[Laurent Montel]

Hi,
I have this problem when I try to use cmake:
lmontel/kde-4.0/kde4/kdelibs-cmake/kdelibs/dcop/dcopclient.cpp
/usr/include/stdlib.h:675: error: declaration of C function 'int 
unsetenv(const char*)' conflicts with
/home/lmontel/kde-4.0/kde4/kdelibs-cmake/kdelibs/config.h:460: error: previous 
declaration 'void unsetenv(const char*)' here
/home/lmontel/kde-4.0/kde4/kdelibs-cmake/kdelibs/config.h:460: error: 
declaration of C function 'void unsetenv(const char*)' conflicts with
/usr/include/stdlib.h:675: error: previous declaration 'int unsetenv(const 
char*)' here

Do you have an idea ?
