#15 How can we build InfoZip (Unzip 6.x) on Mingw/Msys2 ?

How can I build InfoZip (Unzip 6.x) on Mingw/Msys2.. I tried but got error when requiring ioctl.h:

$ make generic_gcc
...
...

gcc -c -I. -Ibzip2 -DUNIX -O3 -DLARGE_FILE_SUPPORT -DUNICODE_SUPPORT -DUTF8_MAYBE_NATIVE -DNO_FCHMOD -DNO_FCHOWN -DNO_LCHOWN -DNO_NL_LANGINFO -DNO_LCHMOD -DHAVE_DIRENT_H -DHAVE_TERMIOS_H -D_MBCS  ttyio.c
ttyio.c:109:12: fatal error: sys/ioctl.h: No such file or directory
 \#  include <sys/ioctl.h>
            ^~~~~~~~~~~~~

How should I solve build InfoZip on Msys2/Mingw ?

How can I build InfoZip (Unzip 6.x) on Mingw/Msys2.. [...]

The secret is hidden in INSTALL (under "Win32 (WinNT or Win9x)":

  [...] for mingw32 and CygWin, GNU Make and win32\Makefile.gcc
  should do the job. [...]

So, a command like the following should work:

  make -f win32/Makefile.gcc

On the bright side, with the next UnZip beta release (6.1c), the
standard Unix build procedure should work as expected in MinGW.
(Basically, "-DUNIX" is replaced by "-DWIN32", but there were also some
other changes to unix/configure and unix/Makefile, so I don't see a
simple way to use the 6.00 Unix builders in that environment.)
