   Does anyone have a manual for "GNU pic version 1.01", or a pointer
   to same?  It works, but I'm having a lot of trouble trying to
   figure out various details from "syntax error at line 33", the
   doesn't-explain-many-things man page, and a 10 year old paper by
   Kernighan describing the original pic.

You can get an up-to-date tech report on pic from AT&T's netlib by
sending mail to netlib@research.att.com with a body of

   send 116 from research/cstr

gpic corresponds quite closely to the version of pic that this
describes.

   Failing that, has anyone persuaded it to understand negative
   numbers?  The input
	   dy = 0.64
	   ymin = 0.12
	   ylow = ymin - dy
	   print ylow
   produces the output (Sun SPARC, IEEE floating point)
	   2.39344e-259
   which suggests that something fishy is going on!

I suspect you've run into a bug in g++ 1.39.  I suggest you get the
current version of groff (1.03), and apply the patches for g++
contained in the groff INSTALL file.
