AC_SYS_LARGEFILE bug in autoconf cvs 20001215

[Frank Zago]

The test behind AC_SYS_LARGEFILE does not work on hpux11, aix 4 and 5.

The following program compiles

#include <sys/types.h>
int a[(off_t) 9223372036854775807 == 9223372036854775807 ? 1 : -1];
int
main ()
{
}

but generate almost the same warnings on both OS:
line 2: warning 602: Integer constant exceeds its storage.
line 2: warning 602: Integer constant exceeds its storage.


Wouldn't it be better to use the following check:

#include <sys/types.h>
int a[sizeof(off_t) == 8 ? 1 : -1];
int
main ()
{
}


Besides that, when the options are correctly detected they are written in
defconfs.h, but are not appended into CFLAGS. Is it the correct
behaviour?

Frank.
