Hi all, <br>
I allways use this "\" to break a long code line into two or more
parts. I think that, in this way, the code is more readable. I've never
had any problem with that and I didn't know it was no neccesary with
gcc. But, could some body tell me if there are compilation problems
with that? In that case, I have to clean it.<br>
<br>
Regards,<br>
Roberto.<br>

<pre wrap="">C question re that fix: (vector/lidar/v.outlier/main.c)
/* Structs' declarations */
struct Map_info In, Out, Outlier, Qgis;
struct Option *in_opt, *out_opt, *outlier_opt, *qgis_opt, *passoE_opt, *passoN_opt, \
*lambda_f_opt, *Thres_O_opt;
is the end of line "\" harmful or treated like whitespace?

It's interpreted as string literal concatenation. In my experience,
it's useful with strings:
Okay for gcc:
fprintf(stderr, "blah blah"
"more blah blah");
More appropriate:
fprintf(stderr, "blah blah" \
"more blah blah");
I'm sure Glynn has details, but that is my understanding. I don't know
if the same issues apply with variable declaration, but it isn't
necessary at least with gcc.
