20dnl Macro to add for using GNU gettext.
21
22dnl Usage: AM_GNU_GETTEXT([INTLSYMBOL], [NEEDSYMBOL], [INTLDIR]).
23dnl INTLSYMBOL must be one of 'external', 'use-libtool'.
24dnl INTLSYMBOL should be 'external' for packages other than GNU gettext, and
25dnl 'use-libtool' for the packages 'gettext-runtime' and 'gettext-tools'.
26dnl If INTLSYMBOL is 'use-libtool', then a libtool library
27dnl $(top_builddir)/intl/libintl.la will be created (shared and/or static,
28dnl depending on --{enable,disable}-{shared,static} and on the presence of
29dnl AM-DISABLE-SHARED).
30dnl If NEEDSYMBOL is specified and is 'need-ngettext', then GNU gettext
31dnl implementations (in libc or libintl) without the ngettext() function
32dnl will be ignored. If NEEDSYMBOL is specified and is
33dnl 'need-formatstring-macros', then GNU gettext implementations that don't
34dnl support the ISO C 99 <inttypes.h> formatstring macros will be ignored.
35dnl INTLDIR is used to find the intl libraries. If empty,
36dnl the value '$(top_builddir)/intl/' is used.
37dnl
38dnl The result of the configuration is one of three cases:
39dnl 1) GNU gettext, as included in the intl subdirectory, will be compiled
40dnl and used.
41dnl Catalog format: GNU --> install in $(datadir)
42dnl Catalog extension: .mo after installation, .gmo in source tree
43dnl 2) GNU gettext has been found in the system's C library.
44dnl Catalog format: GNU --> install in $(datadir)
45dnl Catalog extension: .mo after installation, .gmo in source tree
46dnl 3) No internationalization, always use English msgid.
47dnl Catalog format: none
48dnl Catalog extension: none
49dnl If INTLSYMBOL is 'external', only cases 2 and 3 can occur.
50dnl The use of .gmo is historical (it was needed to avoid overwriting the
51dnl GNU format catalogs when building on a platform with an X/Open gettext),
52dnl but we keep it in order not to force irrelevant filename changes on the
53dnl maintainers.

6
7dnl From Bruno Haible and Sam Steingold.
8
9dnl Sets the HOST_CPU variable to the canonical name of the CPU.
10dnl Sets the HOST_CPU_C_ABI variable to the canonical name of the CPU with its
11dnl C language ABI (application binary interface).
12dnl Also defines __${HOST_CPU}__ and __${HOST_CPU_C_ABI}__ as C macros in
13dnl config.h.
14dnl
15dnl This canonical name can be used to select a particular assembly language
16dnl source file that will interoperate with C code on the given host.
17dnl
18dnl For example:
19dnl * 'i386' and 'sparc' are different canonical names, because code for i386
20dnl will not run on SPARC CPUs and vice versa. They have different
21dnl instruction sets.
22dnl * 'sparc' and 'sparc64' are different canonical names, because code for
23dnl 'sparc' and code for 'sparc64' cannot be linked together: 'sparc' code
24dnl contains 32-bit instructions, whereas 'sparc64' code contains 64-bit
25dnl instructions. A process on a SPARC CPU can be in 32-bit mode or in 64-bit
26dnl mode, but not both.
27dnl * 'mips' and 'mipsn32' are different canonical names, because they use
28dnl different argument passing and return conventions for C functions, and
29dnl although the instruction set of 'mips' is a large subset of the
30dnl instruction set of 'mipsn32'.
31dnl * 'mipsn32' and 'mips64' are different canonical names, because they use
32dnl different sizes for the C types like 'int' and 'void *', and although
33dnl the instruction sets of 'mipsn32' and 'mips64' are the same.
34dnl * The same canonical name is used for different endiannesses. You can
35dnl determine the endianness through preprocessor symbols:
36dnl - 'arm': test __ARMEL__.
37dnl - 'mips', 'mipsn32', 'mips64': test _MIPSEB vs. _MIPSEL.
38dnl - 'powerpc64': test _BIG_ENDIAN vs. _LITTLE_ENDIAN.
39dnl * The same name 'i386' is used for CPUs of type i386, i486, i586
40dnl (Pentium), AMD K7, Pentium II, Pentium IV, etc., because
41dnl - Instructions that do not exist on all of these CPUs (cmpxchg,
42dnl MMX, SSE, SSE2, 3DNow! etc.) are not frequently used. If your
43dnl assembly language source files use such instructions, you will
44dnl need to make the distinction.
45dnl - Speed of execution of the common instruction set is reasonable across
46dnl the entire family of CPUs. If you have assembly language source files
47dnl that are optimized for particular CPU types (like GNU gmp has), you
48dnl will need to make the distinction.
