The C compiler and assembler from ARM ADS 1.x arent't able to create
proper line numbering in the debug information when the source file has
mixed EOL style. I found out that it determines EOL style only
from the first line of source code. I don't know if ARM/Norcroft fixed
this problem on newer versions (RDS).

There are also some problems with C preprocessor definitions. Example:

...
{
    foo(x);
#define DEBUG
    do_something_very_important();
...

#if DEBUG
    bar();
#endif /* DEBUG */
}
...

When the compiler assumes CR/LF line endings the call of
do_something_very_important() can become a part of the macro definition
DEBUG. Especially if macros are used only as flags and never be expanded
as source code (like the DEBUG switch) there won't be a compiler message
(error or just warning) telling that do_something_very_important() will
never be executed.
