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

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.

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

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.
