It looks poor. I think it wouldn't be too hard to write a filter that takes the nroff output and convert the bold/underline to your printer's code.

Postscript is not really an attractive option when your printer does not support it. gs has to send a lot of data to the printer and this makes printing slow. Besides, the gs fonts are ugly, and printer native fonts are usually much better. To make production printing via gs a viable option, you need to add good quality (commercial) fonts, and your printer must have fast data transfer (e.g. ethernet). Not everyone has these.

Cost of tools is not a great concern. I don't think you can get any better C++ compiler for Linux than GCC (but then, that's what I choose to use on other platforms too -- I just plain think it's a good compiler!), but, if "cost is no object", you can surely get good commercial support in other details... I would strongly suggest the Sniff++ classbrowser/development environment; commercial-grade libraries, check out those by Objectspace, those by Modena Software, and those by RogueWave; and, for all-around debugging/profiling/coverage support, Insure++ (my favourite is Sentinel, but they don't release for Linux, darn). As for linux versions, RedHat Professional has a pretty good, stable one, which you can, if you want, get as a part of the Caldera commercial package with various goodies (goodies that may not be very relevant to development work in particular, though). Their Motif, I hear (no personal experience) is also pretty good. I know of several C++ wrappers around Motif, but the only one I have direct experience with (Zinc application framework) I would not recommend unless one had to keep portability of the same sources to Windows, Macintosh, or other GUI's. >We have been using SCO in the past for development, but this project's target >is Linux, and the BOSS wants Linux to be the development platform.

The following patch allowed me to compile kernel 1.2.13 with the new gcc-2.7.2 et. al. It is stolen from Leonard N. Zubkoff, who very kindly posted it a few days ago to the LinuxNet gcc mailing- list (archived at http://homer.ncm.com/).

Nothing in /var/adm/messages or /syslog. The errors were going by so rapidly that I couldn't see them, either |-<. I'm seeing this more and more often lately, even having hung back with .42.
