[bug #55695] [PATCH] Troff outputs garbled file names on MS-Windows

[anonymous]

Follow-up Comment #3, bug #55695 (project groff):

Most Cygwin packages and GNUtilities no longer support native Windows paths, 
unless they happen to pass them verbatim down to open, 
where the file handler may recognize the format and bypass POSIX to Windows
path mapping. 
This is used to provide Windows compatibility in some cases 
and much of the Unix special file system emulation 
e.g. /dev, /mnt, /proc, fifos, ioctls, pipes, sockets, SHM, SysV IPC.
Cygwin now does not differ much from Linux (originally was Solaris): 

$ ls -glo /usr/share/man/man1/addr2line.1*
-rw-r--r-- 1 4658 Feb 12 05:38 /usr/share/man/man1/addr2line.1.gz
$ troff -ms \usr\share\man\man1\addr2line.1.gz 2>&1 > /dev/null | cat -A
troff: fatal error: can't open 'usrsharemanman1addr2line.1.gz': No such file
or directory$
$ troff -ms '\usr\share\man\man1\addr2line.1.gz' 2>&1 > /dev/null | cat -A
troff: fatal error: can't open '\usr\share\man\man1\addr2line.1.gz': No such
file or directory$
$ troff -ms addr2line.1 2>&1 > /dev/null | cat -A
addr2line.1:136: macro error: .TH without .TS H (recovering)$
