On compiling of geanylua with waf there is an issue with an cast as copied in:
../geanylua/glspi_sci.c: In function 'glspi_copy':
../geanylua/glspi_sci.c:470:72: warning: cast from pointer to integer of different size [-Wpointer-to-int-cast]
This is happening on AMD64-arch
should be solved in latest master.
