* src/flex-scanner.h: Indent nested cpp directives.
 2012-05-21 14:48:52 +02:00
Akim Demaille 86b08b49b3 build: do not prototype flex-generated functions. 
Some versions of Flex, possibly modified by the distribution package
maintainers, have incompatible signatures.  Since newer versions of
Flex prototype their functions, avoid the conflicts in that case.
Reported by Stefano Lattarini.
<http://lists.gnu.org/archive/html/bug-bison/2012-05/msg00012.html>.

* src/flex-scanner.h (FLEX_VERSION_GT): New.
Use it to issue prototypes for flex-generated functions only for
versions up to 2.5.31, in accordance with the comment.
See commit dc9701e848.
Use it to define yylex_destroy when needed.
 2012-05-21 14:48:52 +02:00
Akim Demaille 24bb5f8fb7 maint: fix some syntax-check issues. 
* cfg.mk (local-checks-to-skip): Remove
	sc_prohibit_quotearg_without_use, sc_prohibit_strcmp,
	sc_unmarked_diagnostics, sc_useless_cpp_parens.
	(sc_unmarked_diagnostics): Skip DJGPP.
	* data/yacc.c, src/LR0.c, src/closure.c,
	* src/flex-scanner.h, src/gram.c, src/lalr.c,
	* src/print-xml.c, src/print.c, src/print_graph.c,
	* src/reader.c, src/reduce.c, src/tables.c:
	Don't use parens with cpp's defined.
	Remove useless includes.

Joel E. Denny e969014232 global: remove unnecessary horizontal tabs. 
This change was made by applying emacs' untabify function to
nearly all files in Bison's repository.  Required tabs in make
files, ChangeLog, regexps, and test code were manually skipped.
Other notable exceptions and changes are listed below.
* bootstrap: Skip because we sync this with gnulib.
* data/m4sugar/foreach.m4
* data/m4sugar/m4sugar.m4: Skip because we sync these with
Autoconf.
* djgpp: Skip because I don't know how to test djgpp properly, and
this code appears to be unmaintained anyway.
* README-hacking (Hacking): Specify that tabs should be avoided
where not required.

Joel E. Denny 580b892607 Fix memory leaks in scanners generated by at least Flex 2.5.9 and 
later.  Reported by Paul Eggert in
<http://lists.gnu.org/archive/html/bison-patches/2006-11/msg00014.html>.
* src/flex-scanner.h (yylex_destroy): Define for Flex before 2.5.9.
* src/scan-code.l (translate_action): Don't bother invoking
yy_delete_buffer (YY_CURRENT_BUFFER) before creating the first buffer.
(code_scanner_free): Instead of invoking
yy_delete_buffer (YY_CURRENT_BUFFER) directly, invoke yylex_destroy,
which frees more.
* src/scan-gram.l (gram_scanner_free): Likewise.
* src/scan-skel.l (scan_skel): Likewise.
 2006-11-10 05:26:26 +00:00
Joel E. Denny f9bfc42aa7 Clean up scanners a bit. 
* src/flex-scanner.h (FLEX_NO_OBSTACK): New macro that blocks obstack
definitions so gcc won't warn when obstack_for_string is unused.
* src/scan-code.l: config.h and system.h are already #include'd by
scan-code-c.c, so get rid of them here.
* src/scan-gram.l: Likewise.
* src/scan-skel.l: Likewise, and use flex-scanner.h without obstack
definitions rather than duplicating the rest of it.
* src/scan-gram-c.c, scan-skel-c.c: #include "system.h".
 2006-08-10 04:53:04 +00:00
Paul Eggert f2e690d8c3 (STRING_FREE): Don't use FLEX_PREFIX (last_string) 
since last_string is already defined to FLEX_PREFIX (last_string).
 2006-07-09 19:44:34 +00:00
Joel E. Denny 3c40d0b52d * src/flex-scanner.h (yytext): Remove stray `*/' in #define. 2006-06-08 05:33:15 +00:00
Joel E. Denny 9e6688995e * src/flex-scanner.h: For the sake of Flex 2.5.4, don't #define yyleng 
and yytext if they're already #define'd.
* src/flex-scanner.h, src/location.h: Move #include "system.h" to...
* src/scan-code-c.c: ... here.
* src/scan-code.l, src/scan-gram.l: ... and here.  Also #include
<config.h>.
