How old is your copy of GCC? Returning structs worked for as long as I can 
remember.

Returning a structure doesn't seem much more difficult than returning an int 
or a char. If a function is defined as returning a struct, it just needs to 
return a pointer, and the struct definition tells the compiler how many 
bytes there are in the struct and which fields they belong to.
