dtc is only able to track line numbers when the native /include/
directive is used. The #include directive doesn't help it. It should be
added, but until it is the following patch solves the problem:

I've got this patch in my tree. Either Rob or I will push it to Linus in
the next few days.

    dtc: Suppress cpp linemarker annotations
    
    DTC isn't able to parse cpp linemarker annotations, so suppress them in
    the cpp output by adding the -P flag to the cpp options.

Thanks, I'll do something similar in my device-tree.git tree.

Can you show me the original source without mods here, please?
Or is the "..." purely elided comments?

It's supposed to do better than that, I think.
This, from dtc-lexer.l

<*>^"#"(line)?{WS}+[0-9]+{WS}+{STRING}({WS}+[0-9]+)? {
                        char *line, *tmp, *fn;
                        /* skip text before line # */
                        line = yytext;
                        while (!isdigit(*line))
                                line++;
                        /* skip digits in line # */
                        tmp = line;
                        while (!isspace(*tmp))
                                tmp++;
                        /* "NULL"-terminate line # */
                        *tmp = '\0';
                        /* start of filename */
                        fn = strchr(tmp + 1, '"') + 1;
                        /* strip trailing " from filename */
                        tmp = strchr(fn, '"');
                        *tmp = 0;
                        /* -1 since #line is the number of the next line */
                        srcpos_set_line(xstrdup(fn), atoi(line) - 1);
                }

Hrm.  Is this a "that's not in the kernel's copy yet" problem?
Or did this fail to match the offending '# <line> <file>' somehow?
(Like, is that '# 375' really in column 1?)

Thanks,

This is Linux v3.10-rc3 arch/powerpc/boot/dts/virtex440-ml510.dts also

The "#" is in the first column.

BTW I'm using dtc.git 4e76ec796c90d44d417f82d9db2d67cfe575f8ed and not
the kernel copy. 

dtc-lexer.l in my HEAD is identical to the current master
(2e3fc7e9b3a4722a5500afaa9faf7874c61b2e6a) according to git diff.

That's not true; it explicitly does have code to parse the line markers.
I'll have to investigate why it isn't working in this case.

If you apply this patch, then anyone who has switched to #include rther
than /include/ will get incorrect line numbers in dtc error messages.
Admittedly that's a smaller population right now though. Perhaps we
should just do a kernel-wide conversion though.
