dnl zsh_64_BIT_TYPE
|
|
dnl Check whether the first argument works as a 64-bit type.
|
|
dnl If there is a non-zero third argument, we just assume it works
|
|
dnl when we're cross compiling. This is to allow a type to be
|
|
dnl specified directly as --enable-lfs="long long".
|
|
dnl Sets the variable given in the second argument to the first argument
|
|
dnl if the test worked, `no' otherwise. Be careful testing this, as it
|
|
dnl may produce two words `long long' on an unquoted substitution.
|
|
dnl Also check that the compiler does not mind it being cast to int.
|
|
dnl This macro does not produce messages as it may be run several times
|
|
dnl before finding the right type.
