Macro continued with backslash [message #117265]

Hi

I couldn't find a single bug report with backslash, so I write here.

I have some C code which I imported into an eclipse cdt project. The
parser had a problem with macros that are continued like:

#define mydef \
some big value which needs a new line :)

As I also use an old gcc 2.95.3 (cross-compiled with cygwin). I now got
the same error as compile error (and not only indexer error). After
looking on the internet I found that older gcc versions had a problem
with this if the file had the wrong line ending convention (DOS/UNIX).
So I just tried and converted my file from DOS to UNIX (although I'm
working on Windows) and suddenly the parser was happy.

The line ending may not be important in general, but in this case
(macro continuation) there's a bug in the C parser which only works
correctly with UNIX line endings.

Thanks

bye Fabi

Fine, thanks. You could add that this not only works on
Linux but also on Windows when you change the file to
have LF endings. I just mean pointing out that it's not
a Linux<->Windows thing but only about line endings.
