The minimum supported compiler versions now provide a depth-efficient
implementation of std::make_index_sequence, which removes the last
reason to carry a private implementation. In the case of clang, it
appears to have a special compiler intrinsic used to implement its
std::make_index_sequence.
Switch to the compiler-provided version for both gcc and clang.

Rename symbol OGL to DXX_USE_OGL to show that it is a DXX
symbol, not one inherited from a library. Move it to dxxsconf.h to
shorten the command line.
This is a mostly automated transform, but the changes to SConstruct were
manual.

Rename symbol EDITOR to DXX_USE_EDITOR to show that it is a DXX
symbol, not one inherited from a library. Move it to dxxsconf.h to
shorten the command line.

manual.

C casts do not require parentheses. C++ casts require grouping around
the target. Prepare for conversion to C++ casts by adding otherwise
unnecessary parentheses around the target of simple C casts.

Exclude float|double from the second substitution. Including it
rewrites medmisc.cpp in an incorrect way, and excluding it does not
exclude any valid rewrites.

unnecessary parentheses around the target of some C casts.
This pass attempts to process expressions that involve parenthesized or
bracketed subexpressions, but only if those subexpressions do not
themselves contain parenthesized or bracketed subexpressions.

This pass does not attempt to process expressions that involve
any subexpression that can nest arbitrarily, such as parentheses or
