2012-05-25fix regex on armRich Felker-1/+1
TRE has a broken assumption that wchar_t is signed, which is a sane expectation, but not required by the standard, and false on ARM's ABI. i leave tre_char_t as wchar_t for now, since a pointer to it is directly passed to functions that need pointer to wchar_t. it does not seem to break anything. and since the maximum unicode scalar value is 0x10ffff, just use that explicitly rather than using the max value of any particular C type.
2012-03-20upgrade to latest upstream TRE regex code (0.8.0)Rich Felker-68/+31
the main practical results of this change are 1. the regex code is no longer subject to LGPL; it's now 2-clause BSD 2. most (all?) popular nonstandard regex extensions are supported I hesitate to call this a "sync" since both the old and new code are heavily modified. in one sense, the old code was "more severely" modified, in that it was actively hostile to non-strictly-conforming expressions. on the other hand, the new code has eliminated the useless translation of the entire regex string to wchar_t prior to compiling, and now only converts multibyte character literals as needed. in the future i may use this modified TRE as a basis for writing the long-planned new regex engine that will avoid multibyte-to-wide character conversion entirely by compiling multibyte bracket expressions specific to UTF-8.
