In other projects, it is set to # '$srcdir', '$srcdir/..', or '$srcdir/../..'. # # Of course, Automake must honor this variable whenever it calls a # tool from the auxiliary directory. The problem is that $srcdir (and # therefore $ac_aux_dir as well) can be either absolute or relative, # depending on how configure is run. This is pretty annoying, since # it makes $ac_aux_dir quite unusable in subdirectories: in the top # source directory, any form will work fine, but in subdirectories a # relative path needs to be adjusted first. # # $ac_aux_dir/missing # fails when called from a subdirectory if $ac_aux_dir is relative # $top_srcdir/$ac_aux_dir/missing # fails if $ac_aux_dir is absolute, # fails when called from a subdirectory in a VPATH build with # a relative $ac_aux_dir # # The reason of the latter failure is that $top_srcdir and $ac_aux_dir # are both prefixed by $srcdir. In an in-source build this is usually # harmless because $srcdir is '.', but things will broke when you # start a VPATH build or use an absolute $srcdir. # # So we could use something similar to $top_srcdir/$ac_aux_dir/missing, # iff we strip the leading $srcdir from $ac_aux_dir.

They have different dnl instruction sets. dnl * 'sparc' and 'sparc64' are different canonical names, because code for dnl 'sparc' and code for 'sparc64' cannot be linked together: 'sparc' code dnl contains 32-bit instructions, whereas 'sparc64' code contains 64-bit dnl instructions. A process on a SPARC CPU can be in 32-bit mode or in 64-bit dnl mode, but not both. dnl * 'mips' and 'mipsn32' are different canonical names, because they use dnl different argument passing and return conventions for C functions, and dnl although the instruction set of 'mips' is a large subset of the dnl instruction set of 'mipsn32'. dnl * 'mipsn32' and 'mips64' are different canonical names, because they use dnl different sizes for the C types like 'int' and 'void *', and although dnl the instruction sets of 'mipsn32' and 'mips64' are the same. dnl * The same canonical name is used for different endiannesses. You can dnl determine the endianness through preprocessor symbols: dnl - 'arm': test __ARMEL__. dnl - 'mips', 'mipsn32', 'mips64': test _MIPSEB vs. _MIPSEL. dnl - 'powerpc64': test _BIG_ENDIAN vs. _LITTLE_ENDIAN. dnl * The same name 'i386' is used for CPUs of type i386, i486, i586 dnl (Pentium), AMD K7, Pentium II, Pentium IV, etc., because dnl - Instructions that do not exist on all of these CPUs (cmpxchg, dnl MMX, SSE, SSE2, 3DNow! etc.) are not frequently used. If your dnl assembly language source files use such instructions, you will dnl need to make the distinction. dnl - Speed of execution of the common instruction set is reasonable across dnl the entire family of CPUs. If you have assembly language source files dnl that are optimized for particular CPU types (like GNU gmp has), you dnl will need to make the distinction. dnl See .
