cpp produces `#' lines, which aren't valid in Java source. [I don't know
whether or not some compilers accept `#' lines as an extension.]
I use this in my makefiles. Make sure to add .cpp to .SUFFIXES
dependencies (or SUFFIXES variable if using automake).
.cpp:
# # The two-step process is to remove `#LINENUM' strings while
# # keeping line numbers the same as the input file (so long as no
# # #include's).
# # Note that `-P' isn't enough: it doesn't keep line numbers in
# # sync (e.g. it doesn't leave a line corresponding to `#endif').
