Remove src/Makefile.am.
* src/Makefile.am: Rename as... * src/local.mk: this. Prefix all the paths with src/. (AUTOMAKE_OPTIONS): Build object files in the sub dirs. (AM_CPPFLAGS): Find find in builddir/src. (YACC): Move the flags into... (AM_YFLAGS): here. * maint.mk (sc_tight_scope): Disable. It used to bounce to the version in src/Makefile.am which is now part of this very Makefile. * Makefile.am, configure.ac: Adjust. * src/scan-code-c.c, src/scan-code.l: We can no longer rely on include "..." to find files "here": we are no longer in src/, so qualify the includes with src/. * doc/Makefile.am (PREPATH): No longer include the top_builddir prefix. (.x.1): Adjust to be able to create src/foo from the top level Makefile, instead of going bounce to src/Makefile the creation of foo.
