Error on install

[BertLam]

Hi/
When building with the command scons, I get an error:

scons: Reading SConscript files ... scons: done reading SConscript files. scons: Building targets ... gcc -o cpu.o -c -Wall -Werror cpu.c cpu.c:102:1: error: variably modified '__assertion' at file scope [-Werror] COMPILE_ASSERT(((u8 *)&Data.SP) - Data._Bytes == 0x5d); ^~~~~~~~~~~~~~ cpu.c:103:1: error: variably modified '__assertion' at file scope [-Werror] COMPILE_ASSERT(((u8 *)&Data.SREG) - Data._Bytes == 0x5f); ^~~~~~~~~~~~~~ cc1: all warnings being treated as errors scons: *** [cpu.o] Error 1 scons: building terminated because of errors.

Searching for a solution to the problem in Google - did not give answers.
