The package assumes that if the dc program doesn't support -V, it must
not support -e either. This is a bad assumption; DragonFly supports
-e but doesn't support -V. Rather than try to fix a bad conftest, just
remove it completely. There's a previous test for dc presence. If dc
doesn't support -e, let it break during the build rather than before it.
It doesn't take long to build.

foo2zjs is an open source printer driver for printers that use the Zenographics
ZjStream wire protocol for their print data, such as the Minolta/QMS magicolor
2300 DL or Konica Minolta magicolor 2430 DL or HP LaserJet 1020 or HP LaserJet
Pro P1102 or HP LaserJet Pro P1102w or HP LaserJet Pro CP1025nw. These printers
are often erroneously referred to as winprinters or GDI printers. However,
Microsoft GDI only mandates the API between an application and the printer
driver, not the protocol on the wire between the printer driver and the printer.
In fact, ZjStream printers are raster printers which happen to use a very
efficient wire protocol which was developed by Zenographics and licensed by
most major printer manufacturers for at least some of their product lines.
ZjStream is just one of many wire protocols that are in use today, such as
Postscript, PCL, Epson, etc.
