Due to lacking features inAppleClang , some functionalities are suppressed and the following are excluded from build:

1. XConsole.cpp
2. bux::expand_env() inStrUtil.cpp

Unavailable ifAPPLE istrue :

1. XConsole.cpp excluded from build
2. StrUtil.cpp: Callingbux::expand_env() will only get thrown an exception.

Preamble for MacOS build. Expect more changes to come.

And it works.

1. [New] DefineTURN_OFF_LOGGER_ to turn off the logger globally.
2. [New]LOG1(),SCOPELOGXn(),FUNLOGXn() more handy in simple scenarios thanLOG(),SCOPELOGX(),FUNLOGX()
3. [Bug]std::forward<T_Args>() is removed when used thruSCOPELOGX() &FUNLOGX() for both Linux & Windows.
4. [Change] Re-haul to getUnicodeCvt to pass as many test cases as possible in both Linux & Windows, except:
   • In Linux, UTF-16BE without BOM still fails.
   • In Windows, UTF-32 has found no way to pass.

EZScape.cpp definesbux::easy_escape() &bux::easy_unescape() as replacements ofcurl_easy_escape() &curl_easy_unescape() oflibcurl, respectively.

1. [Change] Retain use ofstd::forward<T>() inC_EntryLog::C_EntryLog() anywhere except Windows.
2. [Change] MakeC_NFA::setAction() method template.

1. Allow choosing between system clock and local time (the default) by definingLOGGER_USE_LOCAL_TIME_
2. The path formatting string(s) passed toC_PathFmtLogSnap::configPath() is now used asfmt parameter ofstd::vformat() instead offormat parameter ofstd::strftime()
3. Remove classC_UseLogger and extract the essence into more reusable functionstamp()
4. MacroDEF_FALLBACKABLE_LOGGER_FILES() renamed to shorterDEF_FALLBACK_LOGGER_FILES()
5. Replace-g3 -Og with-O2 to build more efficient library.
