compiling c++ source files

[stefan kersten]

hi,

i have to interface to c++ code and haven't found a way to properly
compile the sources from my GNUmakefile. adding them to
<toolname>_C_FILES doesn't work, because there is no rule to make the
object file.

my current workaround is including the .cpp in a .c file and setting
CC=c++, but i'm sure there is a way to handle this correctly, e.g. by
writing custom rules.

any help would be greatly appreciated, tia,
