+'--with-iconv[=DIR]'
+
+ If your system doesn't provide iconv() function in its native libraries
+(usually libc) or if this function is broken (e.g. older Solaris systems),
+you may want to use libiconv instead. The DIR is the upper path in your
+system which contains lib/ and include/ for libiconv (e.g. /usr/local).
+
+`--without-pthreads'
+
+ If you do not want to compile the programs with POSIX multi-threads
+support you can give --without-pthreads option. In this case all compiled
+programs will work in single thread only.
+
+`--disable-asm'
