The docs only say the following:

<doc>

exec-file [ filename ]
Specify that the program to be run (but not the symbol table) is found in
filename. GDB searches the environment variable PATH if necessary to locate
your program. Omitting filename means to discard information on the
executable file.

</doc>

Right now it errors out if it doesn't find the file.  Inquiry: does
searching the path seem like a sensible thing to do?  It seems to me that
there could be unforseen consequences.
