[Bug-zile] Comments on zile-2.2.59

[Nelson H. F. Beebe]

I've built and installed zile-2.2.59 (and also its predecessor,
zile-2.2.58) on about 25 flavors of Unix in my test laboratory.

On 18 of them, the build and validation was problem free.

On 8 more, I was able to fiddle the build procedure to get a
successful validation and installation.

On 2 others, the builds have failed.

Here is a problem summary.  Complete logs are available on request
from a zile developer, but I won't post them to a list for reasons of
volume and privacy.

------------------------------------------------------------------------
Sun Solaris 7 SPARC:

Compilation and linking with native cc fails because alloca is
undefined.  Change the build procedure to

        env CC=gcc \
            LIBS='-ldl -liberty -lncurses'  \
            LDFLAGS='-L/usr/local/lib -R/usr/local/lib' \
            ./configure && make all check
------------------------------------------------------------------------
GNU/Linux MIPS (Gentoo Base System version 1.4.16):

configure fails with
        checking for getch in -lcurses... no
        configure: error: cannot find either libncurses or libcurses

This system HAS both -lcurses and -lncurses.  The problem is that -ldl
is also needed.  This works:

        env LIBS=-ldl \
            LDFLAGS='-L/usr/local/lib -Wl,-rpath,/usr/local/lib' \
            ./configure && make all check

------------------------------------------------------------------------
Sun Solaris 10 AMD64, IA-32, and SPARC:

Compilation with c99 fails:

        /opt/SUNWspro/bin/c99 -DHAVE_CONFIG_H -I. -I..  
-DPATH_DATA="\"/usr/local/share/zile\""   -I/usr/local/include -c funcs.c

"funcs.c", line 1699: cannot recover from previous errors

This works:

        set path=(/usr/bin /bin /usr/ccs/bin /usr/sfw/bin /usr/local/bin)
        env CC=/usr/sfw/bin/gcc LIBS='-lcurses -liberty' \
            ./configure && /usr/local/bin/make all check

GNU/Linux on PowerPC (Gentoo Base System version 1.12.6)

Same failure as on Gentoo MIPS: same fix too.

Same failure as on Gentoo MIPS: same fix too.

GNU/Linux on SPARC (Gentoo Base System version 1.12.6)

Same failure as on Gentoo MIPS: same fix too.

Since char can be signed or unsigned, it should not be used as a
subscript unless first cast to unsigned int.
