 dnl @synopsis AC_CREATE_TARGET_H [(HEADER-FILE [,PREFIX)]
 dnl
 dnl create the header-file and let it contain '#defines'
 dnl for the target platform. This macro is used for libraries
 dnl that have platform-specific quirks. Instead of inventing a
 dnl target-specific target.h.in files, just let it create a
 dnl header file from the definitions of AC_CANONICAL_SYSTEM
 dnl and put only ifdef's in the installed header-files.
 dnl
 dnl if the HEADER-FILE is absent, [target.h] is used.
 dnl if the PREFIX is absent, [TARGET] is used. 
 dnl the prefix can be the packagename. (y:a-z-:A-Z_:)
 dnl
 dnl the defines look like...
 dnl
 dnl #ifndef TARGET_CPU_M68K
 dnl #define TARGET_CPU_M68K "m68k"
 dnl #endif
 dnl
 dnl #ifndef TARGET_OS_LINUX
 dnl #define TARGET_OS_LINUX "linux-gnu"
 dnl #endif
 dnl
 dnl #ifndef TARGET_OS_TYPE                     /* the string itself */
 dnl #define TARGET_OS_TYPE "linux-gnu"
 dnl #endif
 dnl 
 dnl detail:  in the case of hppa1.1, the three idents "hppa1_1" "hppa1" 
 dnl and "hppa"  are derived, for an m68k it just two, "m68k" and "m"
 dnl
 dnl the CREATE_TARGET_H__ variant is almost the same function, but everything 
 dnl is lowercased instead of uppercased, and there is a "__" in front of
 dnl each prefix, so it looks like...
 dnl 
 dnl #ifndef __target_os_linux
 dnl #define __target_os_linux "linux-gnulibc2"
 dnl #endif
 dnl
 dnl #ifndef __target_os__                     /* the string itself */
 dnl #define __target_os__ "linux-gnulibc2"
 dnl #endif
 dnl
 dnl #ifndef __target_cpu_i586
 dnl #define __target_cpu_i586 "i586"
 dnl #endif
 dnl
 dnl #ifndef __target_arch_i386                
 dnl #define __target_arch_i386 "i386"
 dnl #endif
 dnl
 dnl #ifndef __target_arch__                   /* cpu family arch */
 dnl #define __target_arch__ "i386"
 dnl #endif
 dnl
 dnl other differences: the default string-define is "__" insteadof "_TYPE" 
 dnl
 dnl personally I prefer the second variant (which had been the first in
 dnl the devprocess of this file but I assume people will often fallback
 dnl to the primary variant presented herein).
 dnl
 dnl NOTE: CREATE_TARGET_H does also fill HOST_OS-defines
 dnl functionality has been split over functions called CREATE_TARGET_H_UPPER 
 dnl CREATE_TARGET_H_LOWER CREATE_TARGET_HOST_UPPER CREATE_TARGET_HOST_LOWER
 dnl CREATE_TARGET_H  uses CREATE_TARGET_H_UPPER    CREATE_TARGET_HOST_UPPER
 dnl CREATE_TARGET_H_ uses CREATE_TARGET_H_LOWER    CREATE_TARGET_HOST_LOWER
 dnl
 dnl there is now a CREATE_PREFIX_TARGET_H in this file as a shorthand for
 dnl PREFIX_CONFIG_H from a target.h file, however w/o the target.h ever created
 dnl (the prefix is a bit different, since we add an extra -target- and -host-)

 dnl the instruction set architecture (ISA) has evolved for a small set
 dnl of cpu types. So they often have specific names, e.g. sparclite,
 dnl yet they share quite a few similarities. This macro will set the
 dnl shell-var $target_cpu_arch to the basic type. Note that these
 dnl names are often in conflict with their original 32-bit type name
 dnl of these processors, just use them for directory-handling or add
 dnl a prefix/suffix to distinguish them from $target_cpu
 dnl
 dnl this macros has been invented since config.guess is sometimes
 dnl too specific about the cpu-type. I chose the names along the lines
 dnl of linux/arch/ which is modelled after widespread arch-naming, IMHO.

 *** into an application without using GCC, you have to manually add
 *** \`gcc --print-libgcc-file-name\` to the link command.  We urge you to
 *** upgrade to a newer version of GCC.  Another option is to rebuild your

 dnl @synopsis AC_COMPILE_CHECK_SIZEOF(TYPE [, HEADERS [, EXTRA_SIZES...]])
 dnl
 dnl This macro checks for the size of TYPE using compile checks, not
 dnl run checks. You can supply extra HEADERS to look into. the check
 dnl will cycle through 1 2 4 8 16 and any EXTRA_SIZES the user
 dnl supplies. If a match is found, it will #define SIZEOF_`TYPE' to
 dnl that value. Otherwise it will emit a configure time error
 dnl indicating the size of the type could not be determined.
 dnl
 dnl The trick is that C will not allow duplicate case labels. While
 dnl this is valid C code:
 dnl
 dnl      switch (0) case 0: case 1:;
 dnl
 dnl The following is not:
 dnl
 dnl      switch (0) case 0: case 0:;
 dnl
 dnl Thus, the AC_TRY_COMPILE will fail if the currently tried size
 dnl does not match.
 dnl
 dnl Here is an example skeleton configure.in script, demonstrating the
 dnl macro's usage:
 dnl
 dnl      AC_PROG_CC
 dnl      AC_CHECK_HEADERS(stddef.h unistd.h)
