Mingw64 compile problems with recommended options about paq8pxd HOT 3 CLOSED

P.S. just need -lz into command line

but we have warning below:

g++ paq8pxd.cpp -DWINDOWS -DMT -msse2 -O3 -s -static -o paq8pxd.exe -lz
paq8pxd.cpp:554:0: warning: "MT" redefined
#define MT //uncomment for multithreading, compression only

:0:0: note: this is the location of the previous definition

from paq8pxd.

And my suggestion is to view those warnings via " g++ paq8pxd.cpp -DWINDOWS -DMT -O3 -msse -msse3 -s -static -flto -lz -Wall -Wcast-qual -pedantic -Wextra -Wshadow -o paq8pxd"

warnings.zip

from paq8pxd.

if label about ton of warnings, could You resolve most obvious warnings with flags below and I will try to help with others?

-Wextra
-pedantic

-Weffc++
-Wnon-virtual-dtor
-Wold-style-cast
-Wsign-conversion
