Summary: Wrongful compiler error

Initial Comment:
When compiling the attached file, using this command:

c:\mingw\bin\g++ -O2 -ftemplate-depth-500 -o 
cpp_grammar.o -c cpp_grammar.ii

I get an error in a piece of code that looks like this:

---
struct cpp_grammar: grammar<cpp_grammar> {

    ...

    template <typename ScannerT>
    struct definition:
        cpp_expressions<ScannerT>
    {
        ...
        template < typename ParserT >
        struct brace_block_functor {
            ...
        };

        template < typename ParserT >
        static
        functor_parser<brace_block_functor<ParserT> > // 
line 2304
        brace_block(ParserT const& parser) {
            return brace_block_functor<ParserT>(parser);
        };
        ...
    };
    ...
};
---

The error (sans the "instantiated from" super-spew) says 
this:

---
cpp_grammar.cpp:2306: type/value mismatch at 
argument 1 in template parameter 
   list for `template<class FunctorT> struct 
spirit::functor_parser'
cpp_grammar.cpp:2306:   expected a type, got 
`brace_block_functor'
cpp_grammar.cpp:2306: confused by earlier errors, 
bailing out
---

This is patently wrong. In fact, I have a CygWin with 
GCC 3.0.3 that compiles this program perfectly.

This is with the newest MinGW: 2.0.0-3

Ok, Danny, sorry for the confusion(s). O:-)

So I tried:

c:\mingw\bin\g++ -O2 -ftemplate-depth-500 -o 
cpp_grammar.exe cpp_grammar.cpp -I g:\JCAB\Spirit -
D__GTHREAD_HIDE_WIN32API

Still shows the error.

Salutaciones,

There was a typo in my last message. The define should 
be:
__GTHREAD_HIDE_WIN32API 

(not __GTTHREAD_HIDE_WIN32API).

I'll test again with your cpp_grammar.cpp and spirit 
headers

BTW, you won't be able to test the preprocessor define 
with a preprocessed file. :)

Danny,

I just tried with your fix:

c:\mingw\bin\g++ -O2 -ftemplate-depth-500 -o 
cpp_grammar.o -c cpp_grammar.ii -
D__GTTHREAD_HIDE_WIN32API

And it still shows the error.

Note that this is NOT the c_grammar sample of Spirit. It's 
based on it, yes, but the error happens on new code.

Thanks for checking, though.

Add -D__GTTHREAD_HIDE_WIN32API to command line 
(or put define in appropriate  Boost config header).  I 
have just built the c_grammar  example app from spriit-
1.5.1 with that define and succeeded. (with warning 
about unknown compiler).

The problem is pollution with names from w32 api.  I 
suspect one of the Token names.

 __GTTHREAD_HIDE_WIN32API will be defined by default 
in future mingw releases.

I'll change status of bug report to pending, until the 
define is put into FSF sources.

I couldn't attach the file (the program is BIG, so it would not 
be accepted, not even zipped).

You can download it from here:

http://home.JCABs-Rumblings.com/ftp/cpp_grammar_error.zip

The ZIP file includes the source, preprocessed source and 
the error spew.

Also, the line marked as 2304 in the source fragment I sent 
should be the line of the error: 2306. Copy-paste typo.
