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
* Licensed under the GPLv3
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.
