characters, which have a case mapping. Characters without case
mapping are left unchanged. The mapping is independend from the
locale. Individual character case mappings cannot be reversed,
because some characters have multiple characters that map to them.

to use SLICE_OVERLAPPING instead of GET_SLICE_ORIGIN.
- In str_rtl.c the functions strHeadSlice, strRangeSlice,
strSubstrSlice and strTailSlice have been improved to avoid
(mis)using the string capacity. Now the capacity of a slice is set
to zero. Before the origin of a slice was stored in the capacity.

- This release features the inclusion of the man pages for the seed7
interpreter s7(1) and compiler s7c(1)
- Remove patch included upstream
Changes:
* Interpreter and compiler have been improved to support the option
*l. This option allows adding a directory to the include library
search path (e.g.: -l ../lib).
* The compiler (s7c) has been improved to support the option -b.
With -b the directory of the Seed7 runtime libraries can be
specified (e.g.: -b ../bin).

of the options -l and -b. Now packages can compile the Seed7
compiler without a post install step.
* Additional function variants of parseFile, parseStri and execute
have been added to the library progs.s7i. The new functions allow
a detailed specification of parse and execution options.
* The library gzip.s7c has been improved to decode also blocks with
fixed Huffman codes. This type of block is almost never used since
dynamic Huffman codes compress better.
* The parsing of bigInteger literals has been improved to support
literals with bases other than 10 (e.g.: 16#FEDCBA98765434210_).
* The integer and bigInteger functions str (conversion to string)
have been changed to use lower case characters for digits larger
than 9. Now str(48879, 16) returns "beef" instead of "BEEF".

code for the case that the C floating point division by zero does
not result in Infinity, -Infinity or NaN (not a number).

shifts with negative shift count have been added to the program
chkbig.sd7.

with the clang C compiler.

the analyzing phase) has been removed. On many systems it was a
noop anyway.
* Result variables have been renamed in various libraries and example
programs.

and init_lib_path have been moved from infile.c to the new file
libpath.c.
* The function gen_rtl_array has been defined in the new file
arrutl.c. The function is used in the files cmdlib.c (functions
cmd_pipe2, cmd_pty, cmd_start_process) and prglib.c (functions
prg_exec, prg_fil_parse, prg_str_parse).
* The interpreter/compiler improvements (option -l) and the new
function variants in progs.s7i have been realized with changes in
prg_comp.c, analyze.c, data.h, infile.c, infile.h, info.c, option.h
and s7.c.
* The functions prgExec, prgFilParse and prgStrParse in prg_comp.c
have been improved to support additional parse and execution
options.

bigLShiftAssign, bigRShiftAssign, bigParse, and bigToInt32 have
been improved and bigParseBased has been added.
* To support bigInteger literals with base the file numlit.c has been

is s7.
* Manual, FAQ, read_me files and several example programs were updated to
use the new name of the Seed7 interpreter (s7).

20121125:
- The makefiles and the file setpaths.c were improved to accept the
macros S7_LIB_DIR (Directory with static Seed7 object libraries)
and SEED7_LIBRARY (Directory with the Seed7 include libraries).
Now the build process of a package can call make e.g. with:
make S7_LIB_DIR=/abc/seed7/bin SEED7_LIBRARY=/abc/seed7/lib depend
This way the two paths are defined in version.h. This defines them
as default paths in the interpreter executable and in the compiler.
- An explanation, what a binary Seed7 package should install, was
added to the FAQ. This can be used as guideline for Seed7 packages.
- The description of the times-operator in the manual and in
array.s7i was improved.

os_utime, USE_ALTERNATE_UTIME, INCLUDE_SYS_UTIME, USE_LOCALTIME_R,
USE_LOCALTIME_S, FLOAT_ZERO_DIV_ERROR, CHECK_FLOAT_DIV_BY_ZERO,
ISNAN_WITH_UNDERLINE and HOME_DIR_ENV_VAR. Additionally chkccomp.c
does not depend on the definitions of long_long_EXISTS,
long_long_SUFFIX_LL, __int64_EXISTS, __int64_SUFFIX_LL and
USE_BUILTIN_EXPECT in chkccomp.h.
