Yesterday you posted different #define's and you stated that you had ensured that the blackslash was immediately follwed by a newline.
What about today's #define's? Are you sure that these backslashes are immediately followed by a newline?
If so, this would look like a gcc bug. But yesterday's post showed that you have at least 4 #define's in total with a blackslash but you have only 3 pairs of error messages. I suspect an error on your part involving those 3 #define's. I would expect a compiler bug to be more consistent.
The "bible" states "each occurrence of a backslash character followed by a newline is deleted, thus splicing lines." I'd be surprised if gcc got this wrong.
If nothing else, join the lines yourself in an editor.

VIS(1) BSD General Commands Manual VIS(1)
NAME
vis -- display non-printable characters in a visual format
SYNOPSIS
vis [-bcfhlmnostw] [-e extra] [-F foldwidth] [file ...]
DESCRIPTION
vis is a filter for converting non-printable characters into a visual representation. It differs from 'cat -v' in that the form is unique
and invertible. By default, all non-graphic characters except space, tab, and newline are encoded. A detailed description of the various
visual formats is given in vis(3).
The options are as follows:
-b Turns off prepending of backslash before up-arrow control sequences and meta characters, and disables the doubling of backslashes.
This produces output which is neither invertible or precise, but does represent a minimum of change to the input. It is similar to
``cat -v''. (VIS_NOSLASH)
-c Request a format which displays a small subset of the non-printable characters using C-style backslash sequences. (VIS_CSTYLE)
-e extra
Also encode characters in extra, per svis(3).
-F foldwidth
Causes vis to fold output lines to foldwidth columns (default 80), like fold(1), except that a hidden newline sequence is used,
(which is removed when inverting the file back to its original form with unvis(1)). If the last character in the encoded file does
not end in a newline, a hidden newline sequence is appended to the output. This makes the output usable with various editors and
other utilities which typically don't work with partial lines.
-f Same as -F.
-h Encode using the URI encoding from RFC 1808. (VIS_HTTPSTYLE)
-l Mark newlines with the visible sequence '$', followed by the newline.
-m Encode using the MIME Quoted-Printable encoding from RFC 2045. (VIS_MIMESTYLE)
-n Turns off any encoding, except for the fact that backslashes are still doubled and hidden newline sequences inserted if -f or -F is
selected. When combined with the -f flag, vis becomes like an invertible version of the fold(1) utility. That is, the output can be
unfolded by running the output through unvis(1).
-o Request a format which displays non-printable characters as an octal number, ddd. (VIS_OCTAL)
-s Only characters considered unsafe to send to a terminal are encoded. This flag allows backspace, bell, and carriage return in addi-
tion to the default space, tab and newline. (VIS_SAFE)
-t Tabs are also encoded. (VIS_TAB)
-w White space (space-tab-newline) is also encoded. (VIS_WHITE)

The vis command appears in 4.4BSD.
