this problem is about cvs usage (not cvs itself). cvs always converts
line endings to the format of the system it is installed (or more correct,
built) on. so, line ends will be LF on unix-like systems and CR LF on M$
windows systems. Trevor has cvs from cygwin which is configured to assume
unix-like environment (which sounds rather strange to me, i remember
cygwin can be configured either way). Trevor has no such problems because
his cvs doesn't add extra CR. so, he has LF only in all *.[ch] and the
like files and CR LF in *.ds[pw] files (they are stored this way on the

i can see several possible solutions:

- the best one: switch to gnu/linux like i did ;)

- the next to the best: reconfigure the server to store *.ds[pw] files
  as plain text. Trevor and whoever else will have to reconfigure their
  cvs'es to assume M$ environment (with CR LF).

- another one: use cvs configured for unix environment as Trevor does.
  you'll have some problems about all files except for *.ds[pw] will
  have LF only line ends, which is not what M$ vc++ expects.

- an ungly one i used to use: use a stupid hackish program which
  converts CR CR LF to CR LF.
