We previously replaced local macros with AC_SYS_LARGEFILE, which is unfortunately buggy on some systems and does not correctly set the necessary defines, despite successfully detecting them. This restores the previous macro hacks to acsite.m4

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
