ax_var_timezone_externals

Synopsis

AX_VAR_TIMEZONE_EXTERNALS

Description

Use instead of ‘AC_STRUCT_TIMEZONE’ to determine whether the external timezone variables ‘timezone’, ‘altzone’ and ‘daylight’ exist, defining ‘HAVE_TIMEZONE’, ‘HAVE_ALTZONE’ and ‘HAVE_DAYLIGHT’ respectively (as well as gaining the macros defined by ‘AC_STRUCT_TIMEZONE’).

Rewritten for Autoconf 2.68, and made robust against BSD’s timezone() function, by Daniel Richard G.
