 The mainline version of install.texi includes the following
 after the description of -malign-double:
 
   @strong{Warning:} if you use the @samp{-malign-double}
   switch, structures containing the above types will be
   aligned differently than the published application binary
   interface specifications for the 386.
 
 If that's not strong enough, we could also add:
 
   Code compiled with @option{-malign-double} is not binary
   compatible with code compiled without that switch.
 
 Similar language is now used for warnings about several
 other options.
