***** BUILDING:

This program's build procedure is fairly standard.  Try:

	./configure
	make
	make install

Options to the configure script are up to you.  For details, run:

	./configure --help

Please report build problems at:

	http://sourceforge.net/bugs/?func=addbug&group_id=4664

(yes, even non-Linux problems).


***** TIPS AND PROBLEMS:

- Try to use flex as the lexical analyzer.  The lex scanner is now
separated from the flex version to allow the flex scanner to be
optimized.  It's also a lot harder to diagnose and debug problems
without having full access to the particular platform and its version of
lex being used.  flex is available everywhere --- AT&T lex is not.

- On Solaris, the native lex fails to catch our redefinition of YYLMAX
early enough, which leads to possible buffer overflows.

- On Linux systems (and possibly others) configure may fail if lex is
  a synomyn for flex.  To fix, do the following:

	make distclean
	./configure --with-flex
	make

- On HP-UX several problems exist when using configure. Try the following
  to solve this:

	CFLAGS='-Ae -DYYCHAR_ARRAY' CURSES_LIBS=-lHcurses ./configure

- On Tru64, formerly known as Digital Unix, formerly known as DEC OSF/1,
  the system-supplied libcurses causes cscope to terminate itself
  immediately as it comes back to foreground after being suspended by
  the user (Ctrl-Z). Using GNU Ncurses instead of OSF1 curses works
  around the problem. According to the lynx and ncurses people, this
  is a design problem of curses vs. signal handling, at the heart of it.

- Solaris 2.8 on Intel hardware may not work using the vendor's curses
  implementation.  Using the free NCurses should help.

- Some ancient Unix filesytems supported only 14 characters in 
  filenames.  cscope no longer cares for that by default.  If you want
  to run it on such a system, #define the macro SHORT_NAMES_ONLY manually
  (there's a definition in global.h you can uncomment).

<div class='commit-subject'>xfs: bump up reserved blocks in xfs_alloc_set_aside</div><div class='commit-msg'>Setting aside 4 blocks globally for bmbt splits isn't all that useful,
as different threads can allocate space in parallel.  Bump it to 4
blocks per AG to allow each thread that is currently doing an
allocation to dip into it separately.  Without that we may no have
enough reserved blocks if there are enough parallel transactions
in an almost out space file system that all run into bmap btree
splits.
