Stu,

OK, I agree that 'space character' means 0x20, not just white space, so your language is specific enough on that.

Regarding stripping off the escape, 5.6.1 says

    "Neither the leading backslash character nor the terminating white space is considered to be part of the identifier. Therefore, an escaped identifier \cpu3 is treated the same as a nonescaped identifier cpu3."

For example, the following is a legal declaration

  typedef enum {\typedef , \enum , \uwire } T;

but the following is not

  typedef enum {\typedef , \enum , \T } T;

Brad,

The proposal specifies the "backslash and space characters", which I felt
was clear which type of whitespace is being used.  I would be fine with
amending the proposal to say "backslash ( \ ) and space (ASCII 0x40)
characters".

Personally, I feel that if the user specifies an escape where it is not
needed, tools should still return the name with that escape.

As far as I know, the standard is silent on whether tools are allowed to
strip off the escape when it is not needed, which, IMHO, makes it illegal to
do so.  If stripping off the escape is specified somewhere, then I am OK
with amending the proposal to refer to that text for when .name returns the
escaped form of the label.

Both points will need to be discussed at the May 11 conference call, since
the e-mail vote already has a mix of yes and no responses.
