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.

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:
