Synopsis: Function attributes for C++ constructors confuses g++ frontend

State-Changed-Why:
    This is a duplicate of PR 6992. The new parser which
    will hopefully be in gcc3.4 will handle this correctly,
    but it will probably not be fixed in gcc3.3 or 3.2.2.

>Description:
Putting __attribute__((dllexport))  infront of a C++ class constructor confuses the frontend. Moving it to the end of the constructor fixes the problem. Typical output is:

C:\sonals\scratch>g++ -c export.cpp
export.cpp:5: parse error before `const'
export.cpp:7: warning: `dllexport' attribute ignored
export.cpp:7: declaration does not declare anything
export.cpp:7: parse error before `)' token
export.cpp:24: prototype for `MyExpo::MyExpo(const char*)' does not match any
   in class `MyExpo'
export.cpp:1: candidates are: MyExpo::MyExpo()
export.cpp:1:                 MyExpo::MyExpo(const MyExpo&)
export.cpp:29: definition of implicitly-declared `MyExpo::MyExpo()'
export.cpp:29: declaration of `MyExpo::MyExpo()' throws different exceptions
export.cpp:1: than previous declaration `MyExpo::MyExpo() throw ()'
>How-To-Repeat:
g++ -c export.cpp
