Changelog:
Changes since 2.2.1
1. src/slsmg.c: Call SLutf8_enable if UTF8 mode has not been setup.
2. src/slutty.c: Allow the hook that gets called when the read
function gets interrupted to change the read file descriptor.
Before, if this happened, the SLang_getkey function would return
SLANG_GETKEY_ERROR.
3. lib/slsh/print.sl: Turn off buffering of the pager pipe.
4. modules/tm/*.tm: A couple of typos corrected (John Houck)
5. src/slmath.c: The round function was not correctly rounding values
between 0.5 and 1.0.
6. src/slstdio.c,slclass.c: If a call to fwrite produces errno=EPIPE,
then do not bother trying the write again.
7. modules/fork-module.c: Use WIFCONTINUED only if it is defined.
8. slsh/Makefile.in: Change the order of the libraries such that the
newly built ones will be found first. (Markus Hennecke)
9. src/slagetput.inc: Avoid possible access violation when using a
range array as an index.
10. doc/tm/rtl/lists.tm: Documented the optional argument to the
list_to_array function (Manfred Hanke).
Changes since 2.2.0
1. modules/socket-module.c: glibc-2.8 removed the h_addr macro.
2. src/slclass.c: Call clearerr before performing the
stdio_fread/fwrite functions.
3. src/slstdio.c: typeof in the fputs intrinsic fixed (n instead of dn
was compared to 0).
4. src/slscanf.c: sscanf will treat NaN and Inf in a case-insensitive
manner. Also, the NaN([a-zA-Z0-9]*) form is also supported.
5. src/slang.h: SLclass_set_aelem_init_function was missing from the
API.
6. src/slmath.c: The expm1 and log1p functions were returning NaN when
given Inf arguments.
7. src/slmath,c: log1p(-1) produced nan instead of -inf.
8. configure: Added pkg-config support (based upon a debian patch sent
to me by Luca Bigliardi).
9. doc/tm/rtl/math.tm: Updated the help for set_float_format and added
documentation for the get_float_format function.
10. autoconf/slangpc.in: Added URL and Libs.private entries to the
slang.pc pkg-config file.
11. src/slang.h: prototype for SLang_create_array1 missing from slang.h.
12. src/slcurses.c: Added debian patch that adds support for
additional graphics characters (DIAMOND, DEGREE, etc...).
13. doc/tm/slang.tm: Added a small section about arrays of arrays.
14. src/slang.c: __builtin_expect is used for the stack functions if
compiled with gcc.
15. src/*.c: A few public variables were not explicitly initialized
to 0. Apparantly not doing so causes them not be be exported from
the windows DLL.

This changes the buildlink3.mk files to use an include guard for the
recursive include. The use of BUILDLINK_DEPTH, BUILDLINK_DEPENDS,
BUILDLINK_PACKAGES and BUILDLINK_ORDER is handled by a single new
variable BUILDLINK_TREE. Each buildlink3.mk file adds a pair of
enter/exit marker, which can be used to reconstruct the tree and
to determine first level includes. Avoiding := for large variables
(BUILDLINK_ORDER) speeds up parse time as += has linear complexity.
The include guard reduces system time by avoiding reading files over and
over again. For complex packages this reduces both %user and %sys time to
half of the former time.
version, and packages should switch to it as they are deemed compatible.
blurb:
S-Lang is a C programmer's library that includes routines for the rapid
development of sophisticated, user friendly, multi-platform applications.
The S-Lang library includes the following:
- Low level tty input routines for reading single characters at a
time, as well as low-level terminal-independent routines for
manipulating the display of a terminal.
- Keymap routines for defining keys and manipulating multiple
keymaps.
- High level screen management routines for manipulating both
monochrome and color terminals. These routines are very efficient.
- Routines for reading single line input with line editing and recall
capabilities.
- Searching functions: both ordinary searches and regular expression
searches.
- An embedded stack-based language interpreter with a C-like syntax.
- A malloc debugging package
