ncurses 5.6 under UWIN 4.1

[Howard Bryden]

Guys,

Environment:
        UWIN (Unix For Windows) 4.1
        Compiler                        MinGW   3.2.0
        NCurses 5.6.

Desktop:
        O/S:            Windows XP Pro, SP2
        Processor:      Pentium P4
        Memory: 512MB

Some things I had to work through to get NCurses installed and running in this environment.

1. For some reason, the nanosleep() API is cranky in this environment, for values (of ts1.tv_nsec as per the configure script) less than 500000 it terminates but thereafter it hangs.  Maybe configure should have some sort of background timer that could kill this (and declare the test a failure).

2. The form of usage_string in progs/tic.c source had to be recast to the following, gcc gagged at the original form:

static const char *usage_string = "[-e names] [-o dir] [-R name] [-v[n]] [-V] [-w[n]] [-1aCcfGgILNrsTtUx] source-file\n";

3. In test/test.priv.h, I ran into colliding definitions for "struct stat" when building for wide-character support.  I had to modify this include file at around line #210 as follows:

#include <signal.h>     /* include before curses.h to work around glibc bug */

#if USE_WIDEC_SUPPORT && defined(__MINGW32__)
#include <sys/stat.h>   /* Avoid colliding definitions for struct stat HDB */
#endif

#if defined(HAVE_XCURSES)
...

4. In ncurses/curses.priv.h, I again ran into colliding definitions for "struct stat" when building for wide-character support.  I had to modify this include file at around line #250 similarly:

...
#undef _XOPEN_SOURCE_EXTENDED
#define _nc_bkgd    _bkgd
#define wgetbkgrnd(win, wch)    *wch = win->_bkgd
#define wbkgrnd     wbkgd
#endif

#if USE_WIDEC_SUPPORT && defined(__MINGW32__)
#include <sys/stat.h>   /* Avoid colliding definitions for struct stat HDB */
#endif

#include <curses.h>     /* we'll use -Ipath directive to get the right one! */
...

5. The distribution perhaps should include an implementation of wcwidth().

6. Just for fun, here's the terminfo(5) database I developed for use with the VT100 emulator as implemented by the U/WIN environment:
