Mea culpa.

Chalk this up to incorrect mucking with the trunc function on my
side, a very old bug here.  Apologies.

And for me under Solaris 8, gcc-3.4.2 or Sun cc Forte 7, 32- or 64-bit, 
with options as recommended in R-admin.

I suspect this is caused by unsafe compiler options.

Works for me with R-2.0.0, Solaris 5.7 (UltraSparc), gcc-3.2.3, 32-bit.
So you have to specify compiler version, OS version, R version etc. much 
more precisely.

(gdb) p pnorm(-10.1, 0.0, 1.0, 0, 1)
$42 = NaN(0xf)
Expected: -0
(gdb) p pnorm(-10.0, 0.0, 1.0, 0, 1)
$43 = -0
Good.
(I know this is not a typical usage.)

(gdb) p pnorm(-10.1, 0.0, 1.0, 0, 1)

Expected: -0

(gdb) p pnorm(-10.0, 0.0, 1.0, 0, 1)

Good.
