Yes, gcc does the same, but it isn't true that the padding can be ignored 
in this case, because if you read an array of structs from a disk file, 
you still need to take it into account, because the slack space is 
written to the file.  The DJGPP FAQ list discusses this issue at somewhat 
more length in section 22.9.
