Hi, I was trying to compile slimlock with gcc 4.7, but got the following error message:

$ make g++ -Wall -I. -I/usr/include/freetype2 -pthread -DPACKAGE=\"slimlock\" -DVERSION=\"0.11\" -DPKGDATADIR=\"/usr/share/slim\" -DSYSCONFDIR=\"/etc\" -c cfg.cpp -o cfg.o g++ -Wall -I. -I/usr/include/freetype2 -pthread -DPACKAGE=\"slimlock\" -DVERSION=\"0.11\" -DPKGDATADIR=\"/usr/share/slim\" -DSYSCONFDIR=\"/etc\" -c image.cpp -o image.o g++ -Wall -I. -I/usr/include/freetype2 -pthread -DPACKAGE=\"slimlock\" -DVERSION=\"0.11\" -DPKGDATADIR=\"/usr/share/slim\" -DSYSCONFDIR=\"/etc\" -c panel.cpp -o panel.o panel.cpp: In member function ‘void Panel::WrongPassword(int)’: panel.cpp:219:18: error: ‘sleep’ was not declared in this scope make: *\ [panel.o] Error 1

please review my patch. Thanks

Well, I was about to make this very pull request. I have users that confirm this fix on Gentoo.
