The results are almost the same as those at the stable release.
The zipped config.log is placed here:
http://www.geocities.jp/tmacchant2/config.log.20160411.zip
The previous reply to Hans I made a mistake to extract the memcpy related part.
I apologize for that.
configure:9591: result: no
configure:9591: checking for memcpy
configure:9591: gcc -o conftest.exe -g -O2  -I/usr/local/include  -L/usr/local/lib -lcerf conftest.c  >&5
conftest.c:86:6: warning: conflicting types for built-in function 'memcpy'
 char memcpy ();

Seeing configure output screen: one can see that:

  WARNING: Could not find a working version of snprintf.
           If a user provides gnuplot with an improper format statement
           then a buffer overflow and/or segfault can result.
           Please consider providing snprintf via an external library.
The above is very strange. Checks of many fucntions are no.
