Re: [Qemu-devel] [PATCH v3 00/15] GCC warning flags

[Andreas Färber]

Hi Blue,

Some of the warnings currently enabled are applicable only to C and  
Objective-C code, but gcc warns for C++:

cc1plus: warning: command line option "-Wold-style-definition" is  
valid for C/ObjC but not for C++
cc1plus: warning: command line option "-Wold-style-declaration" is  
valid for C/ObjC but not for C++
cc1plus: warning: command line option "-Wnested-externs" is valid for  
C/ObjC but not for C++
cc1plus: warning: command line option "-Wstrict-prototypes" is valid  
for C/ObjC but not for C++
cc1plus: warning: command line option "-Wmissing-prototypes" is valid  
for C/ObjC but not for C++

Any idea how to handle this configure/rules.mak-wise? Split  
QEMU_CFLAGS into QEMU_CPPFLAGS and QEMU_CFLAGS/QEMU_CXXFLAGS?

Regards,
Andreas
