Here's the first proposed patch. I verified that
- on HP-UX 11.00 and 11.31, Solaris 7 and 10, it causes statvfs() to be used
again:
checking for statvfs function (SVR4)... no
becomes
checking for statvfs function (SVR4)... yes
Since the check_f_blocks_size is in place, it proves that this causes
f_blocks to be 64-bit.
- on MacOS X 10.5, it causes fsusage.o to call statfs$INODE64 instead of
statfs, thus also supporting large volumes.
