Top-level configure.ac searches for tgetent, finds it in ncurses, so 
adds -lncurses to TERMLIBS.

It has both a <termcap.h> and <ncurses/termcap.h> (from different 
packages).  Both disagree with pcterm.c about what the prototypes of 
these functions should be (const-ness, mostly, but also the return type 
of tput()).

Changing line 39 of terminal.c to this:

#elif defined (HAVE_TERMCAP_H) && !defined (__MINGW32__)

does indeed allow ginfo.exe to build.

It does not really work, though.  It behaves as if its stdout had been 
redirected, because the isatty() check fails.  Looks like that "MinGW 
applications inside a MSYS2 Mintty fail detecting tty" issue.
