Not any compiler I've worked with in the last few decades. That sort of 
went out with CP/M.  Way back when bytes were worth their weight in gold 
someone declared 'short  ObjNum;'  That's rather important since that is 
the number of objects that can be handled by the system including 
incidents, comments, persons, vehicles, alerts and so forth. Being signed 
and 16 bits the maximum value is 32767

It got by for an amazingly long time but as larger, busier sites came 
along the system ran out of object number. It wasn't pretty.

Edit a number of files to make it an unsigned short and you get 65535. It 
was close a couple of times but with some sophisticated reuse strategies 
there never was a disaster.

Why not make it an int? Even with a signed int 2147483647 wouldn't be a 
problem. Because an int is 32 bits.  Every struct, every XDR encoding, 
database, and so forth would have to be modified so we crossed our 
fingers. In DB2 SMALLINT is 16 bits, INT is 32 bits. SQL Server is the 
same. Both of them use BIGINT for 64 bits.
