dnl _AC_SYS_LARGEFILE_MACRO_VALUE
dnl
dnl The following macro overrides the autoconf macro of the same name
dnl with this custom definition. This macro performs the same checks as
dnl autoconf's native _AC_SYS_LARGEFILE_MACRO_VALUE, but will also set
dnl AM_CPPFLAGS with the appropriate -D defines so additional configure
dnl sizeof checks do not fail.
