// Override the alignment definitions from cyg_type.h. ARM only allows 4 
// byte alignment whereas the default is 8 byte.

//-----------------------------------------------------------------------------
// Define the standard variable sizes

// The ARM architecture uses the default definitions of the base types,
// so we do not need to define any here.
