Rename symbol USE_TRACKER to DXX_USE_TRACKER 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.
git grep -l USE_TRACKER -- '*.h' '*.cpp' | xargs sed -i -e 's/^#ifdef \(USE_TRACKER\)$/#if DXX_\1/' -e 's/#\(el\)\?if \(.*\)defined(\(USE_TRACKER\))/#\1if \2DXX_\3/'
Rename symbol USE_SDLMIXER to DXX_USE_SDLMIXER 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 and
inferno.cpp were manual.
git grep -l USE_SDLMIXER -- '*.h' '*.cpp' | xargs sed -i -e 's/^#ifdef \(USE_SDLMIXER\)$/#if DXX_\1/' -e 's/#\(el\)\?if \(.*\)defined(\(USE_SDLMIXER\))/#\1if \2DXX_\3/'
This pass only targets commonly used standard types.
s/(\(\s*\(\(un\)\?signed\|int\|char\|short\|long\|float\|double\|s\?size_t\|\(u\?int[[:digit:]]\+_t\)\)\s*\*\)\s*)\s*(/reinterpret_cast<\1>(/g
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.
This pass does not attempt to process expressions that involve
any subexpression that can nest arbitrarily, such as parentheses or
brackets. It also works only on commonly used standard types.
(int) a->b; // changed
(int) a[b]; // not changed

Both callers of ReadIniArgs need the string removed afterward. Prior to
8fb9a0f, only the parser for `-ini` needed the string removed. The
caller for the automatic ini file ended and destroyed the container. As
of 8fb9a0f, the container persists. Leaving the string in the container
causes a bad error message if the command line is rejected.
It is bad form to have ReadIniArgs pop, but the caller push. However,
the two callers use different signatures for emplace_back(), so unifying
the push would require calling a suboptimal emplace_back. Choose the
lesser evil of unbalanced push/pop.
