43cc55dd2f 1) Rev.1.35 of dd.c has a more serious regression. It backs out rev.1.31,
thus breaking systems with unpolluted <sys/stat.h>'s.

2) Back out an initialisation of a variable in BSS.

3dc2f99bef Previous commit broke dd(1)'s I/O summary when it's terminated by a
signal.  Fix it by adding an explicit call to summary() in terminate()
(it was previously called implicitly by exit() because summary() was
registered with atexit()).  summary() is supposed to be signal-safe--
it handles SIGINFO almost exclusively--so this should be safe.

708c7f49eb Add iseek= and oseek= aliases for the preexisting skip= and seek=
operands.  Can _YOU_ tell skip= and seek= apart with 100% accuracy
every time?

This also seems to make us option-for-option compatible with the

277eda1860 Do proper constification in args.c. This shuts up -Wcast-qual (thanks,
bfumerola for that pointer!) in GCC complaining about losing a const.

While I'm here, might as well mark in the Makefile that I'm the

a12ece1af8 Make count=0 set cpy_cnt to -1, which is slight overloading, but makes
what I was trying to do work much better (ie at all.  I could have sworn
it was working...) Fix a SEEK_SET to be SEEK_CUR, and make Bruce's
lseek() test work correctly.

4e25c183b5 Let count=-something fail, while count=0 may succeed, thus making dd(1)
useful as a seeking-tool as well as its many other uses.  Previously,
dd(1) would succeed with count=0, but wouldn't get to the point that
blocks were to be read/written. This is a more useful behavior, and
this specific case doesn't seem to be handled by POSIX.

4c16a85a3f Even more cleanups to dd(1). This is probably the culmination of the
BDEification process of dd(1). Most of the changes are from BDE's archive.
Support for negative offsets is gone again, but the case where you
lseek() onto byte -1 of something from a negative offset using seek/skip
is fixed; if you end up on -1, you won't get a false positive lseek failure.
  The biggest changes are to data types (more size_t, for instance) and
argument parsing. skip/seek on /dev/{,k}mem now occurs (instead of "read
until you reach the offset") due to mem devices now being D_DISK. Some
const things are now correctly declared as such, and the "case table"
building is better. The only thing that seems to be left to make dd(1)
everything TOG wants it to be is l10n.

a9f7b5ee69 Make a bit more headway with dd's argument parsing, etc. get_bsz() is
renamed get_num() since it's not just about block sizes. skip and
seek can be any offset, including negative, now. Some style bogons are fixed.

b54fa2acf7 Exit with a nonzero status if we get killed by a SIGINT. POSIX.2
specifies exiting with a zero status if the file was copied
successfully, and with a nonzero status if an error occurred.  We
are too sloppy to tell if the file was copied successfully when we
get killed by a SIGINT, but it is unlikely to have been.  Added a
comment about related sloppiness (calling exit() from a signal
handler).
