18    Description:
20    I eliminated coreEnv from compInfo.  Access to the "Core" structure is
21    now done via the ordinary static environment that is context to each
22    compilation unit.
24    To this end, I arranged that instead of "structure Core" as "structure
25    _Core" is bound in the pervasive environment.  Core access is done via
26    _Core (which can never be accidentially rebound because _Core is not a
27    legal surface-syntax symbol).
29    The current solution is much cleaner because the core environment is
30    now simply part of the pervasive environment which is part of every
31    compilation unit's context anyway.  In particular, this eliminates all
32    special-case handling that was necessary until now in order to deal
33    with dynamic and symbolic parts of the core environment.
35    Remaining hackery (to bind the "magic" symbol _Core) is localized in the
36    compilation mananger's bootstrap compiler (actually: in the "init group"
37    handling).  See the comments in src/system/smlnj/init/init.cmi for
38    more details.
40    I also tried to track down all mentions of "Core" (as string argument
41    to Symbol.strSymbol) in the compiler and replaced them with a
42    reference to the new CoreSym.coreSym.  Seems cleaner since the actual
43    name appears in one place only.
45    Binfile and bootfile format have not changed, but the switchover from
46    the old "init.cmi" to the new one is a bit tricky, so I supplied new
47    bootfiles anyway.
