--enable-__cxa_atexit enable __cxa_atexit for C++
--enable-decimal-float={no,yes,bid,dpd}
enable decimal float extension to C. Selecting 'bid'
--with-gnu-ld assume the C compiler uses GNU ld [default=no]
--with-plugin-ld=[ARG] specify the plugin linker
--with-long-double-128 use 128-bit long double by default
- --with-gc={page,zone} choose the garbage collection mechanism to use with
