>Environment:
Linux 2.6.18-6-k7
gcc version 4.1.2
GDB was configured as "i486-linux-gnu"
>Description:
Cannot use fifos to pass commands to gdb via -x option, eg using bash syntax as below

gdb -x <(echo "set <something>") <program>

There is an explicit check in openp for a regular file - can this be changed to also allow a fifo?
>How-To-Repeat:
Run something like this at a bash prompt:

gdb -x <(echo "set height 0") ls
>Fix:
openp in source.c needs to also allow fifos when checking is_regular_file.
