You have to be very careful with the combination of \f(CW and \fP on Solaris 10 nroff
That should be OK, as \f(CW - which is now \f(CR - is used only if \n(.g is nonzero, i.e., only if it's groff and not traditional troff.
I toyed with using \f[CW] instead of \f(CW to underscore that it's groff-specific. However, that might be overkill given the number of non-*roff programs that read these files.
