Thanks for your information.  This was not the problem of slang 
compilation/installation but lynx compilation.

Then I investigated a bit and found that you are (perhaps) right.

Let me explain why I made mistakes. My Debian system (potato) has 
Slang 1.3.9 (call slang1) and Slang with Japanized patch based on 
Slang 1.2.2 (call slang1-ja).

Furthermore we (Debian JP) have an yet experimental Slang with
Japanized patch based on Slang 1.4.0 (call slang1.4-ja).

So it is very easy for me to test with slang1, slang1-ja and 
slang1.4-ja and furthermore slang1 and slang1-ja can be installed
at the same time, and slang1 and slang1.4 can be too.
(But the fact seems not to be so simple.)

In case I installed slang1 and slang1-ja (or slang1.4-ja), we 
had libslang.so, /usr/include/slang.h of slang1 and libslang-ja.so, 
/usr/include/slang/slang.h of slang1-ja (or slang1.4-ja).  

So to make lynx compiled with Slang 1.2.2 we changed configure 
script a bit so that it would find libslang-ja and this was simple 
change but configure seemed to find /usr/include/slang.h of 
Slang 1.3.9 not /usr/include/slang/slang.h of Slang 1.2.2.

I found in LYCurses.c;

#if SLANG_VERSION > 10306
    SLsmg_touch_screen ();
#endif

So LYCurses.c misunderstand that the present Slang satisfies
#if SLANG_VERSION > 10306
but the Slang library does not know SLsmg_touch_screen at all.

I believe that this is the reason of 'SLsmg_touch_screen' problem.
(Perhaps my explanation is very hard to understand, sorry)

And '-ldl' problem it seems the experimental slang1.4-ja might
be wrong.  See the following output of ldd:

Note the original contains "libdl"

        libdl.so.2 => /lib/libdl.so.2 (0x40195000)

but Slang 1.4.0 does not!

Well, very sorry but these are due to my system and not
bug of lynx at all.
