In commit be8759e68b337524c056b8bb757ea68c9996d863, a buffer overflow
was fixed in erlc and the erlc_SUITE:arg_overflow/1 test case was
added. That test cases invokes erlc with 10000 -D options, which will
result in 'erl' being invoked with more than 30000 arguments.
On some platforms, the test case will fail for the wrong reason:
* 64-bit Linux kernels before 2.6.23 limit the number of arguments in
an excvp() call to 16383. (See "Number of arguments and maximum length
of one argument" in http://www.in-ulm.de/~mascheck/various/argmax/.)
* The command shell in Windows limits the size of the command line to
8191 characters.
Depending on the platform, pass a different number of -D options
to erlc. Since the size of the options does not matter for this
test case, make the options as short as possible by generating
numbers in base 36.

Check buffer operations and increase the size of the buffer used for
holding command line arguments, since the "-D" switch will be expanded
into 3 arguments when passed to erl.

On Windows, the ERL_TOP environment variable contains
a path that only is valid for cygwin-enabled programs,
such as 'make'. It is not meaningful to pass the value
of $ERL_TOP in the -I option to the Erlang compiler,
because the Erlang emulator does not interpret cygwin
paths correctly. Therefore, -include("test_server.hrl")
will fail to find test_server.hrl.
Work around the problem by using -include_lib().

* cf/compile_warning_as_error:
Add option -Werror in erlc(1)
compile: add flag warnings_as_errors to treat warnings as errors
compile.erl: remove trailing whitespace
OTP-8382 The -Werror option for erlc and the compiler option
warnings_as_errors will cause warnings to be treated as errors.
(Thanks to Christopher Faulet.)

Like in gcc, this option treats warnings as errors.

The MIB compiler in the snmp applications formats its warnings slightly
differently, so we'll need to update the regexp that should match the
expected output.
