make check and postscript output in R 1.7.1

I'm sorry, I neglected to provide version information.

In fact, I see the same result from make check on two different 
systems: Solaris 2.7 and OS X 10.2.6.

The "-0.00" values in reg-plot.ps.save are the kinds of values I saw 
in postscript files generated by R 1.7.0, i.e., prior to the fix of 
PR#3132.

In particular, in his r-help message on 2003-5-29 on the topic 
"Postscript query: plotting long vectors", Peter Dalgaard noted "If 
you want to use rlineto, you need to round *before* differencing." 
Values like "-0.00" could result from rounding *after* differencing, 
could they not?

My earlier message was from the OS X build. This is from make check on Solaris:
comparing 'reg-plot.ps' to '../../source/tests/reg-plot.ps.save' ...100c100
< 663.53 0 l
---

 663.53 -0.00 l

104c104
< 0 -7.20 l
---

 -0.00 -7.20 l

On the OS X system:
configure --prefix=/Users/macq/R/R-1.7.1 \
    --enable-R-shlib --with-blas="-framework vecLib" --with-lapack \
    CPPFLAGS="-I/sw/include" LDFLAGS="-L/sw/lib"

On the Solaris system
source/configure --prefix=/erd/statistic/apps/R/R-1.7.1\
    --with-tcl-config=/erd/statistic/apps/R/tcltk/tcl8.3.3/unix/tclConfig.sh\
    --with-tk-config=/erd/statistic/apps/R/tcltk/tk8.3.3/unix/tkConfig.sh\
    --enable-R-shlib PERL=/apps/gnu/perl5/perl5.8.0/bin/perl

It's telling us that your machine gives different output from *all* the
other machines that were checked in the beta-test period.   So what
machine is this that no one beta tested?   (In future please do
participate in the beta test so your unusual system gets tested.)

As Rob G has reported this from FreeBSD earlier today it is probably
already fixed in R-devel (it is for him).  Fortunately the difference is
in this case negligible.

 I think this might be telling us that reg-plot.ps.save needs to be
 updated for the new version of postscript().
