Introduce test target.
Changes in version 1.4
* Symbol aliases
The `--symbol' option has been extended to allow for defining
symbol aliases. Aliases are useful for declaring reserved
words such as `__restrict' or `__inline'. For example,
the option `--symbol __restrict:=restrict' instructs cflow
to treat `__restrict' exactly as `restrict'.
* New syntactic class: qualifiers
Tokens in this class can legitimately appear in place
of C qualifiers, such as `static' or `inline'. This class
is useful for some compiler-depending keywords, such as
`__extension__' in gcc. The usual declaration of this symbol
is `--symbol __extension__:qualifier'.
* Speed up recursive call detection.
* Fix parsing of typedefs after `struct'.
* Fix the output of branch marks in tree mode.
* Fix processing of static inline functions (RH bug 650716).
Version 1.3, 2009-07-11
* Optimize symbol tables.
New symbol tables considerably improve the program performance.
* Bugfixes.
Version 1.2, 2007-06-29

* THANKS: Add Louis Bertrand.

* src/output.c (set_level_mark): Fix allocation condition
(output): Remove erroneous initialization of level_mark.

Fix bug spotted by Jerry St.Clair: incorrect handling of
global/static and static/static name clashes.
* src/parser.c (declare): Do not report name clashes
if a static symbol overrides another static or global.
(add_reference): Do not refer to static symbols if
-i^s was used.
* src/symbol.c: Change organization of the symbol table: the
table entry contains struct table_entry, which contains a pointer
to the head of the symbol list associated with the entry. Thus,
deletions from the table can be handled in a more natural manner.
All functions changed to reflect the change.
(unlink_symbol): New function.
(delete_symbol): Rewritten using unlink_symbol
(delete_statics): always call static_processor
* THANKS: Add Jerry St.Clair.
* tests/Makefile.am: Add hiding.at, multi.at
* tests/testsuite.at: Likewise.
* tests/hiding.at: New testcase
* tests/multi.at: New testcase
* tests/fdecl.at, tests/funcarg.at, tests/include.at,
tests/nfarg.at, tests/nfparg.at, tests/parm.at,
tests/ssblock.at: Uniformly begin AT_SETUP text with a lowercase
letter.

charting control flow within the program.
GNU cflow is able to produce both direct and inverted flowgraphs for C
sources. Optionally a cross-reference listing can be generated. Two
output formats are implemented: POSIX and GNU (extended).
Input files can optionally be preprocessed before analyzing.
