Normally, programs that use autoconf have an `m4' directory that
contains all M4 files with macros used in `configure.ac'. The program
`aclocal' then scans `configure.ac' and copies the macros from the
files in the `m4' directory into `aclocal.m4'.
Currently, `aclocal.m4' is manually maintained in lilypond. One
solution is to move the various macros contained in this file into
smaller files in the `m4' directory so that `aclocal' can build
`aclocal.m4'. The other solution is to copy the AX_CXX_COMPILE_STDCXX
macro directly to `aclocal.m4'.
