RE: Problem with user defined commands

A small correction in the test.gdb file which I pasted earlier. This is the 
correct one... bash-3.2$ cat test.gdb
define wsfoo
printf "wsfoo\n"
end
define foo
wsfoo
end
define bar
printf "bar\n"
end

Hi All,
 
User defined commands gets messed up if a definition has a name starting with 
"ws" and called from another definition. Is it a known defect? Any workarounds?
 
bash-3.2$ cat test.gdb
define wsbaz
printf "wsbaz\n"
end
define foo
wsbaz
end
define bar
printf "bar\n"
end
 
bash-3.2$ ./gdb

We figured that the problematic code was this

 command line structure for them.  */
  if ((p_end - p >= 14 && !strncmp (p, "while-stepping", 14))
  || (p_end - p >= 8 && !strncmp (p, "stepping", 8))
