Also, if the header is bad, exit with a non-zero status.
Other calls to Brdline in the tree, by category:
Reading symbol name from object file:
./cmd/5l/obj.c:486: name = Brdline(f, '\0');
./cmd/6l/obj.c:535: name = Brdline(f, '\0');
./cmd/8l/obj.c:564: name = Brdline(f, '\0');
./libmach/sym.c:292: cp = Brdline(bp, '\0');
Reading archive header line (fixed, short):
./cmd/gc/lex.c:287: if((a = Brdline(b, '\n')) == nil)
./cmd/gc/lex.c:303: if((p = Brdline(b, '\n')) == nil)
Reading object file header line (fixed, short):
./cmd/ld/lib.c:421: line = Brdline(f, '\n');
Reading undefined symbol list (unused code):
./cmd/ld/lib.c:773: while((l = Brdline(b, '\n')) != nil){
Implementing Brdstr:
./libbio/brdstr.c:36: p = Brdline(bp, delim);
The symbol names ones will cause a problem loudly if they
fail: they'll error out with symbol name too long. This means
that you can't define an enormous struct without giving the
type a name and then stick it in an interface, because the
type's symbol name will be too long for the object file.
Since this will be a loud failure instead of a silent one,
I'm willing to wait until it comes up in practice.

Background: The current spec is imprecise with respect to the parsing ambiguity
for composite literals: It says that the ambiguity arises when the TypeName form
of the LiteralType is used. The following code:
if (B) {} ...
is not using the TypeName form (but the parenthesized TypeName form) and thus
could be interpreted as:
if ((B){}) ...
instead of
if B {} ...
Both compilers and gofmt choose the latter interpretation. One could fix the
spec by making the clause regarding the parsing ambiguity more precise ("...using
the _possibly parenthesized_ TypeName form of the LiteralType..."). The alternative
(chosen here) is to simply disallow parenthesized literal types. Except for a single
test case (test/parentype.go) there appears to be no Go code under $GOROOT containing
parenthesized literal types. Furthermore, parentheses are never needed around a
literal type for correct parsing.

of syscall.Syscall and syscall.SYS_KILL.
In RTEMS, there is no syscall.Syscall support, but it does
support POSIX signals. So, if this testcase is changed to use
syscall.Kill, then it would run fine on RTEMS, when using gccgo.

remove the print statements.
This change is because of the port of gccgo to RTEMS.
These tests use the GCC DejaGNU framework. In some cases,
the tests need to be run on qemu where the status code
cannot be sent back to DejaGNU, so it prints the exit status
by putting a wrapper around the exit and abort calls.
This testcase closes the stdout, and hence prohibits DejaGNU
from knowing the status in such cases, and causes this test
to be wrongly declared as a failure.

This shortens, simplifies and regularizes the code significantly.
(Improvements to reflect could make another step.)
Passes all.bash.
One semantic change occurs: The String() method changes
behavior. It used to run only for string formats such as %s and %q.
Instead, it now runs whenever the item has the method and the
result is then processed by the format as a string. Besides the
regularization, this has three effects:
1) width is honored for String() items
2) %x works for String() items
3) implementations of String that merely recur will recur forever
Regarding point 3, example from the updated documentation:
type X int
func (x X) String() string { return Sprintf("%d", x) }
should cast the value before recurring:
func (x X) String() string { return Sprintf("%d", int(x)) }

interface conversions from type assertions:
convT2I, assertI2T, etc.

useful in a mathematical context)

this is a version synthesized from rsc's, dean's and my
versions. changes and updates:
- embeds the retval script and pushes a new version to the
device if needed
- passes arguments correctly to the program on the device
- export GOARCH, GOTRACEBACK and GOGC from the local
environment to the device.
- added times.out support to run-arm
enabled a few tests that are now passing and moved the
GOGC=off workaround to run-arm.
