Olly Betts de1327fb15 Allow defining __cplusplus on the command line
The default value for __cplusplus is now 199711L rather than defining
it to have the value __cplusplus.

Olly Betts 8a9628e2b9 Use strchr/Strchr for single character searches
This can be more efficient than using strstr/Strstr with a single
character search string.

GCC is able to optimise strstr() with a single character literal
search string to strchr(), but clang doesn't, and likely no compiler
can for Strstr() (unless some sort of inter-object optimisation such
as LTO is used) since the literal string is in a different source file
to the strstr() call.

Olly Betts de4e3b454e Fix #ifdef and #ifndef to work inside a %define
Previously they were silently ignored in this context (but #if defined
already worked here if you need a workaround which works for older
versions).

Olly Betts 043bdf5677 Copy over missing parts of macro expansion code
We need to insert newlines for a multi-line macro invocation, and
we shouldn't leak memory.

Olly Betts f8a766295c Handle `)` in command line interface filename
SWIG now handles an interface filename specified on the command line
which contains a closing parenthesis `)`, and more generally with
attributes to `%include` and `%import` which are quoted and contain
parentheses.

Olly Betts 74d12d8c4c Don't report "Warning 202: Error: ..."
An invalid preprocessor expression is reported as a pair of
warnings with the second giving a more detailed message from the
expression evaluator.  Previously SWIG prefixed the second message
with "Error:" - that was confusing as it's actually only a warning
by default so we've now dropped this prefix.

Before:

x.i:1: Warning 202: Could not evaluate expression '1.2'
x.i:1: Warning 202: Error: 'Floating point constant in preprocessor expression'

Now:

x.i:1: Warning 202: Could not evaluate expression '1.2'
x.i:1: Warning 202: Floating point constant in preprocessor expression

See #1465

Olly Betts be4065531e Add suggestion to check block delimiter
The fix for #217 means that blocks of target code delimited by { } with
'#' comments in now give errors (previously these lines were quietly
discarded).

The fix is generally to use %{ %} delimiters instead, so suggest this
might be the issue in the error message to help users hitting this issue
with wrappers which were apparently working before.

Olly Betts ce90ff6a77 When reporting an error for a construct which hasn't been terminated
when the end of the file is reached, report it at the start line rather
than "EOF" as then tools like editors and IDEs will take you to a
generally more useful place for fixing the problem.
