Assembler error

I am seeing this assembler warning using gcc version 2.95.3 20010315:
{standard input}:332: Warning: using `%si' instead of `%esi' due to `w' uffix{standard input}:332: Warning: using `%ax'
insteadof `%eax' due to `w' suffix
 

This is while compiling commands/trigger.c and it happens in
CreateTrigger().  The actual assember instruction is marked below.  Any
ideas if our code is somehow triggering this warning?

I believe it is this line of C code:
   TRIGGER_CLEAR_TYPE(tgtype);
--> if (stmt->before)       TRIGGER_SETT_BEFORE(tgtype);
