This option is not supported with gcc < 4.2

I don't see -fno-strict-overflow listed at all in the manual for gcc 4.1.
So maybe it is better to use -fwrapv, which is defined thus:

`-fwrapv'
     This option instructs the compiler to assume that signed arithmetic
     overflow of addition, subtraction and multiplication wraps around
     using twos-complement representation.  This flag enables some
     optimizations and disables others.  This option is enabled by
     default for the Java front-end, as required by the Java language
     specification.
