Tom,

  I worked on the GNIS (Geographical Names Information System) files
back to a couple years ago.

  By writing a C/script code, I am pretty sure that you can extract the
specific info into either GRASS site_lists or label file. However, I recompiled
the GNIS into a RDBMS (INFORMIX) database. The advantage to use the relational
database engine is that a RDBMS could handle multi-variables or multi-attributes
very efficient. The GNIS file, by its nature, is designed to associate each
individule geographical point to multi-attributes. With a RDBMS engine, the
users could search the particular interesting points by specifying the search
criteria by county, quad, feature, or combination of them, etc.

  Jim Farley's DBsql-tools in GRASS4.1beta release could be used to
interface the RDBMS to GRASS.

  By the way, I wrote a specific interface with Informix 4GL and C for
our version of GNIS database in Informix which could directly generate either
GRASS label files or site_lists file. However, It's been a long time, some
features of this code have been changed and more important, this interface is
designed exclusively for the specific recompilation of GNIS in our site.

  For more questions, please send e-mail directly to me.
