If you install a new version of DEC Unix, you should rebuild GCC to pick up the new version stamp. -Note that since the Alpha is a 64-bit architecture, cross-compilers from -32-bit machines will not generate code as efficient as that generated -when the compiler is running on a 64-bit machine because many -optimizations that depend on being able to represent a word on the -target in an integral value on the host cannot be performed. Building -cross-compilers on the Alpha for 32-bit machines has only been tested in -a few cases and may not work properly. - @samp{make compare} may fail on old versions of DEC Unix unless you add @option{-save-temps} to @code{BOOT_CFLAGS}. On these systems, the name of the assembler input file is stored in the object file, and that makes
