Whenever I use gv on a PostScript file as in

It is not obvious what limitations or errors are affecting the displayed

of issuing the command with the qualifier
$ gv filename.ps 2> /dev/null
However: the Warning messages whilst occasionally very esoteric nearly always
include the form
Warning: Missing charsets in String to FontSet conversion
Warning: Cannot convert string
"-*-Helvetica-Bold-R-Normal--*-120-*-*-P-*-ISO8859-1" to type FontStruct

Is there some additional fonts package or group of packages that I could
usefully incorporate into my Cygwin setup that
would reduce warnings when using gv? (And maybe improve the rendering of
outputs.)
My directory /usr/share/fonts/microsoft/ contains 120+ ttf links, though none
looking anything like helv*.
I doubt it. I'm not familiar with gv, but this looks like you're
trying to process documents that incorporate Helvetica, in a way that
requires having the font files, without having the font files.
Helvetica is a trademark, and the font files are under copyright, so
no Cygwin package is going to be able to include the fonts or even
include substitutes with matching filenames.
You *might* be able to add symlinks from the missing Helvetica files
to more readily available metric-identical alternatives you already
have access to, e.g. Arial, MS Sans Serif, or Liberation Sans.
Otherwise I suspect you need to either avoid processing files that
incorporate fonts you don't own, or buy copies of the relevant
Helvetica typefaces.
Something I might try first is researching how fontconfig can allow
you to set up substitutions.
