st: xi:reg command dropping numerous dummies

Statalist,

I am using the xi:reg to simulate a fixed-effects (xtreg, fe)
regression, so that I am able to use importance weights, in the form:

xi: reg var1 var2 var3 i.code [iweight=var4]

However, I am finding that many of dummies (a little under half) are
being dropped by Stata.  This doesn't impact upon the results that I
am interested in (the coefficients of var2/var3), but I would be
interested to know why this is happening and how it could potentially
be fixed.

Many thanks,

Robert Gaskell
