Although argc and argv are never read after the longjmp is complete,
gcc is not clever enough to see that and needlessly warns about it.
So add volatile to silence the compiler.

o Old-style K&R declarations have been converted to new C89 style
o register has been removed
o prototype for main() has been removed (gcc3 makes it an error)
o int main(int argc, char *argv[]) is the preferred main definition.
o Attempt to not break style(9) conformance for declarations more than
they already are.
o gc some #ifdef sun ... #endif code
Approved by: arch@, new style(9)
o Add consts where appropriate.
o Rename some variables that were shadowing global declarations.
o Remove register storage-classes.
o Make errmsg a const, so we can just set error messages instead
of using sprintf/strcpy.
o Set WARNS=2

which is also called from handle_hup(), uses stdio(3). Furthermore,
this means that calling exit(3) (via quit()) there is required to
flush the buffer write_file() was working on.

error caused by the -1 being on the wrong side of the comparison.
This would not cause an overflow, as near as I can tell, because we
truncate later anyway. We'd just fail to get a diagnostic for 1024
and 1025 byte file names.
This will make a number of things easier in the future, as well as (finally!)
avoiding the Id-smashing problem which has plagued developers for so long.
Boy, I'm glad we're not using sup anymore. This update would have been
insane otherwise.
/usr/src/bin. Note that some patches are still needed in that directory.
I (Joerg) finished most of Philippe's cleanup. /bin/sh will still
need *allot* of work, however.
