38861be639 Use __builtin_trap instead of null pointer dereference to abort 
This fixes a warning from Apple's clang compiler:

6e37389fcd doc: Don't fail if manpages fail to build 
Even with installed asciidoc and xsltproc the build will fail if
xsltproc cannot find the required stylesheet
http://docbook.sourceforge.net/release/xsl/current/manpages/docbook.xsl.

Ignore such errors until there is a better check in configure.

f491eb6188 Simplify tanh and logistic functions and precompute function tables 
Both functions are called very often, so computing the table values
at program start should be faster than computing them on demand.
