I recently posted a question about a problem I was having with rpcgen,
where it would mangle `directive' lines that had line continuation
characters as follows:
%#define PRINTRECORD(fp,r,t) { \
% fprintf(fp,RECFORMAT, \
% UID_LEN, r->userid, \
% COUNT_LEN, r->count, \
% SEED_LEN, r->seed, \
% VAL_LEN, r->val, \
% TIME_LEN, t); \
%}
(The purpose of doing the above was to wind up with macros in the
generated files that spanned several lines.)
At any rate, after considerable head-scratching I've traced the
problem to GNU CPP's habit of removing the backslash/newline pairs in
all circumstances. It turns out that rpcgen runs cpp as a front-end,
and on FreeBSD, unlike SunOS and Solaris 2, the GNU preprocessor is
used. So if anyone had tried to investingate this behavior, there's
no need.

P.S. I enjoy using FreeBSD and am pushing it for server use here in
the lab I administer. We have 8 machines in various roles with an
aggregate of about 60GB of disk space on these 8 machines. Apart from
little puzzles (like the above) from time to time, everything works
well.
