The orginal code (before the patch) is correct. It handles the following
special case in flex.skl (lines 377-373) in which flex preprocessing is
performed on a multi-line C macro:


#define YY_DO_BEFORE_ACTION \
        YY_G(yytext_ptr) = yy_bp; \
%% [2.0] code to fiddle yytext and yyleng for yymore() goes here \
        YY_G(yy_hold_char) = *yy_cp; \
        *yy_cp = '\0'; \
%% [3.0] code to copy yytext_ptr to yytext[] goes here, if %array \
        YY_G(yy_c_buf_p) = yy_cp;


If I hadn't handled that special case by placing a trailing '\' character at
the end, then the resulting C macro would be interrupted by a comment.  What
errors are you getting?
