automake confusing c and c++

[Philippe Trottier]

Hello,

      I have built some conditional in the configure script so that I 
would build on the needed/wanted libraries, and it seems that automake 
get confused about my hello_cc.cc to be the source as it tries to 
compile a "hello_cc.c" anyone can point me at what I am doing wrong ?

noinst_PROGRAMS =

if COND_CC
noinst_PROGRAMS += hello_c
hello_c_SOURCE = hello.c
endif

if COND_CXX
noinst_PROGRAMS += hello_cc
hello_cc_SOURCE = hello_cc.cc
endif
