GDB's man page source (in gdb.texinfo) contains:
@t{++}
The @t{...} part is supposed to display the wrapped text with a
fixed-width font. The texi2pod.pl script currently doesn't handle
@t{...}, so it appears as-is in the man page:
You can use GDB to debug programs written in C, C@t{++}, Fortran and Modula-2.
gcc's version of texi2pod.pl (at contrib/texi2pod.pl in gcc's repo)
replaces @t{...} with the wrapped text as-is, which I think is an
acceptable behavior. The fixed-width font distinction is not really
important for a man page, where the text will be displayed with whatever
font the user is using.
Import the line that does that from gcc's version.
I have verified that there is no other, unwanted change in man pages
generated in binutils' and GDB's doc, with this patch applied.
