I have come across this problem before (well, a similar manifestation
anyway).

On HP workstations, the regcmp and regex routines required by the File
selection Box to do its pattern matching are not in the standard C
library, but in (you guessed it...) libPW.a . Therefore, when using an
HP (9000/340 in my case), you must link with this library. 

This library is definately not present or required for Suns, and I
can't speak for Dec machines, but assume that it is also not required
there.
