Phil, what you say about being undocumented is completely true for all
early GCC releases that included SGI STL.  What you say about using
"-pthread" or "-mthreads" or whatever verses defining _NOTHREADS is
finally true in GCC 3.1 and beyond.

GCC 3.0.X still allowed a user to define _NOTHREADS.  Dan was asking
about 3.0.2.  There are known SMP bugs in that release.  Due to my
fault, I don't think they were all ever fixed on the 3.0.X branch.

Loren
