passing flags to C compiler but not to C++ compiler

[Vincent Torri]

hello

in my sources, i have both C and C++ files. Something like

my_lib_la_SOURCES = foo.c foo.cpp

I want to pass, for example, -Wdeclaration-after-statement to gcc. Hence,
when compiling foo.cpp, i have the warning :

cc1plus.exe: warning: command line option '-Wdeclaration-after-statement'
is valid for C/ObjC but not for C++

How can I remove this warning when compiling c++ files ?

thank you
