SDL autoconf problem

I'm having a problem using the sdl.m4 autoconf file from libsdl in my project. 
When it tries to run a test program it adds `sdl-config --cflags` to CFLAGS, 
which includes a -I flags that is necessary to find the required headers, but 
configure compiles it with g++ and can't find the headers. Changing it to use 
CXXFLAGS fixes the problem.

I believe this is autoconf's problem because the documentation says that 
AC_TRY_RUN takes a C program - it should be using a C compiler, which would 
look at CFLAGS.
