pkgsrc/devel/bison: Makefile PLIST distinfo
Update to 2.5.1:
* Noteworthy changes in release 2.5.1 (2012-06-05) [stable]
** Future changes:
The next major release will drop support for generating parsers in K&R C.
** yacc.c: YYBACKUP works as expected.
** glr.c improvements:
*** Location support is eliminated when not requested:
GLR parsers used to include location-related code even when locations were
not requested, and therefore not even usable.
*** __attribute__ is preserved:
__attribute__ is no longer disabled when __STRICT_ANSI__ is defined (i.e.,
when -std is passed to GCC).
** lalr1.java: several fixes:
The Java parser no longer throws ArrayIndexOutOfBoundsException if the
first token leads to a syntax error. Some minor clean ups.
** Changes for C++:
*** C++11 compatibility:
C and C++ parsers use "nullptr" instead of "0" when __cplusplus is 201103L
*** Header guards
The header files such as "parser.hh", "location.hh", etc. used a constant
name for preprocessor guards, for instance:
# define BISON_LOCATION_HH
#endif // !BISON_LOCATION_HH
The inclusion guard is now computed from "PREFIX/FILE-NAME", where lower
case characters are converted to upper case, and series of
non-alphanumerical characters are converted to an underscore.
With "bison -o lang++/parser.cc", "location.hh" would now include:
# define YY_LANG_LOCATION_HH
#endif // !YY_LANG_LOCATION_HH
*** C++ locations:
The position and location constructors (and their initialize methods)
accept new arguments for line and column. Several issues in the
documentation were fixed.
** liby is no longer asking for "rpl_fprintf" on some platforms.
** Changes in the manual:
*** %printer is documented
The "%printer" directive, supported since at least Bison 1.50, is finally
documented. The "mfcalc" example is extended to demonstrate it.
For consistency with the C skeletons, the C++ parsers now also support
"yyoutput" (as an alias to "debug_stream ()").
*** Several improvements have been made:
The layout for grammar excerpts was changed to a more compact scheme.
Named references are motivated. The description of the automaton
description file (*.output) is updated to the current format. Incorrect
index entries were fixed. Some other errors were fixed.
** Building bison:
*** Conflicting prototypes with recent/modified Flex.
Fixed build problems with the current, unreleased, version of Flex, and
some modified versions of 2.5.35, which have modified function prototypes.
*** Warnings during the build procedure have been eliminated.
*** Several portability problems in the test suite have been fixed:
This includes warnings with some compilers, unexpected behavior of tools
such as diff, warning messages from the test suite itself, etc.
*** The install-pdf target work properly:
Running "make install-pdf" (or -dvi, -html, -info, and -ps) no longer
halts in the middle of its course.
