C++ #error not recognized

[thalenth]

The C++ #error directive is not recognized, and makes codemetre to ignore file with following message:
*** Error: file "foo.cpp" is not written in c++ (line 23 : unknown prefix)

This directive is usefull when combining with #ifdef to disallow unexpected combinations.

"#error" C/C++ directive, like "#warning" directive, is currently recognized by codemetre, with some limitation. In fact, one shall consider that #error/#warning are macros with a single string argument, even though this argument is not delimited with double quotes.

Until this limitation is removed, I strongly advise you to double-quote your strings as to codemetre to recognize them and not being fooled by single quotes or whatever. This means changing your code from

#warning this platform is unknown
#error I think it'll crash codemetre

to

#warning "this platform is unknown"
#error "I think it'll crash codemetre"
