[Bug-zile] zile 2.3.20: program_name missing

[Christian Weisgerber]

zile 2.3.20 fails to build here on OpenBSD:

...
../lib/libgnu.a(error.o)(.text+0x320): In function `error':
: undefined reference to `program_name'
../lib/libgnu.a(error.o)(.text+0x4f0): In function `error_at_line':
: undefined reference to `program_name'
...

As lib/error.c says:

/* The calling program should define program_name and set it to the
   name of the executing program.  */
extern char *program_name;

Currently src/main.c defines only

char *prog_name = PACKAGE;
