             Bug #: 51067
           Summary: cpp.texi Line Control node not mentioning #, trailing
                    integers
    Classification: Unclassified
           Product: gcc
           Version: 4.6.3
            Status: UNCONFIRMED
          Severity: normal
          Priority: P3
         Component: preprocessor
        AssignedTo: unassig...@gcc.gnu.org
        ReportedBy: k...@freefriends.org


In the Line Control node in cpp.texi, I do not see any mention of the
(long-used) form
# 1 "foo.c"
That is, # instead of #line.

Also, I do not see any description of the trailing integers now sometimes
present in the CPP output, as in:
# 1 "/usr/include/bits/sys_errlist.h" 1 3 4

(I looked around in the rest of the manual and other manuals too, to no avail. 
If the info is present elsewhere, at least an xref from Line Control would seem
useful.)

Thanks,
Karl
