Return to fprint.c CVS log

Up to [Development] / xfs-cmds / xfsprogs / db

Bunch of portability related changes to xfsprogs.  Includes some code to
allow db/mkfs/repair to be used on Mac's (maybe useful for dual boot), &
some code to build on IRIX too (useful for purify-ing xfs_repair only).
Fix compiler warning on newer versions of gcc.
