No feedback in 3 months about the -Wno-attributes option and the current
behavior of GCC so closing.

(In reply to comment #12)
 This happens with Qt4 Win32 as well - lot of warnings - warning: inline
 function... attribute ignored. All that's needed is a -Wno-inline-dllimport
 type of flag to mingw to suppress these warnings. 

This is current (gcc-4.2) behaviour.
What exactly is wrong with using -Wno-attributes to suppress the warnings.

Danny


// warn-inline-dllimport.c
__declspec (dllimport) void f1();

// inline definition (silently) overides earlier dllimport declaration
inline  void f1() {}

// inline  dllimport in definition emits warning
//  both can't be true.  
inline  __declspec (dllimport) void f2 () {}

void b()
{
  f1(); 
  f2();
}


compiling as:
gcc -Wall -c warn-inline-dllimport.c
produces:

warn-inline-dllimport.c:8: warning: inline function 'f2' declared as dllimport:
attribute ignored


compiling as:
gcc -Wall -Wno-attributes -c warn-inline-dllimport.c
gets rid of the attribute warning

type of flag to mingw to suppress these warnings. 

Specifying dllimport to inline functions seems reasonable though - If the
compiler won't inline the function (that's just a hint) people will want to
specify dllimport to avoid linker errors, or no?

On today's trunk, your example no longer gives warnings. Instead it compiles,
then fails with:
C:\tmpG++ -Wall -W test.cpp 
c:\tmp/ccOGb2M9.o:test.cpp:(.text+0x1e): undefined reference to
_imp___ZN1TC1Ev'
c:\tmp/ccOGb2M9.o:test.cpp:(.text+0x3b): undefined reference to
`_imp___ZN1TD1Ev'
collect2: ld returned 1 exit status

OK to close?
Is that what you want
