handling of program_transform_name. * configure.in: Test for "unlink" and "delete", define USE_DELETE_FOR_UNLINK if only the latter is found. Not expected to be triggered on UNIX/POSIX systems. * acconfig.h (USE_DELETE_FOR_UNLINK): Undef here, provide comments. Update for autoconf 1.118: * gdbinit.in: New file, created from old .gdbinit. * .gdbinit: Deleted. * aclocal.m4 (GAS_GDBINIT): Deleted. * configure.in: Don't use it. Instead, generate .gdbinit from gdbinit.in. Don't substitute cpu_type, obj_format, emulation, atof. Switched order of AC_LINK_FILES arguments. Use AC_PREREQ to ensure that older versions of autoconf aren't used. * Makefile.in: Added @configure_input@ line. (configure): Deleted rule. [regenerated conf.in, configure]
