Form feed character in header files

[zeroSpammingIsBadtype]

Hi,

On Cygwin, most of the header files for gcc and g++ used UNIX style
line breaks, so I've been replacing these (by copying into Wordpad
from Notepad and then copying out again) with Windows-style line
breaks. However, this doesn't get rid of instances of character 12
(Form Feed).

Is there any reason why it wouldn't be safe to delete these and thus
improve the readability of the files? Does the compiler just ignore
them?

Thanks,

James McLaughlin.

This is not a question related to C++. Try posting in an appropriate
newsgroup. However, I think replacing line-breaks would not affect the
compilation in any way.

Paragraph 2.2 of the C++ standard says:

The basic source character set consists of 96 characters: the space
character, the control characters representing horizontal tab,
vertical tab, form feed, and newline, ...

I.e. they are safe, and not ignored.

Yes it is. See ISO 1488 para 2 2.2
Try posting in an appropriate
newsgroup.
This group is the right one.

compilation in any way.

The answer is that it's 'safe' to either leave the form-feed
characters there or to remove them (IF none of them is the only
delimiter between tokens). Except within literals, whitespace
is automatically skipped during translation. 'Form-feed' is listed
by the standard as a required member of the execution character set.

My mistake. I apologise. I did not know about this. Thanks Mike.
