Previously, they could match the literal digit, + e.g., the stated r.e. might have matched `abc1'. + +* Empty subexpressions are always valid (POSIX leaves this undefined). + +* Simplified rules for ^ and $ being anchors. + +* One minor speedup (rewriting the C procedure `pop_failure_point' as a + macro again). + +* Bug fixes involving: + - Declarations in regex.h and non-ANSI compilers. + - Bracket expressions with characters between 0x80-0xff. + - Memory leak in re_match_2 on systems requiring `alloca (0)' to + free alloca'd storage. + +* Test and documentation files moved into subdirectories. + +Version 0.10 (9 Sep 92) + +* `obscure_syntax' is now called `re_default_syntax'. + +* `re_comp's return type is no longer `const', for compatibility with BSD. + +* POSIX syntaxes now include as much functionality as possible + (consistent with the standard). + +* Compilation conditionals normalized to what the rest of GNU is + migrating towards these days. + +* Bug fixes involving: + - Ranges with characters between 0x80 and 0xff, e.g., [\001-\377]. + - `re_compile_fastmap' and the sequence `.*\n'. + - Intervals with exact counts, e.g., a{5}. + +* Changed distribution to use a standard Makefile, install the info + files, use a configure script, etc. + +Version 0.9 + +* The longest match was not always chosen: `a*|ab' didn't match `aab'. + |
