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.

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".

f2e690d8c3 (STRING_FREE): Don't use FLEX_PREFIX (last_string)
since last_string is already defined to FLEX_PREFIX (last_string).

3c40d0b52d * src/flex-scanner.h (yytext): Remove stray `*/' in #define. 2006-06-08 05:33:15 +00:00

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>.
