1 - str2offset() no longer accepts negative numbers since offsets are by nature positive. 2 - introduced str2unum() for the command line parser that accepts numericals which are not supposed to be negative, so that it will properly complain on apparent bad uses and mistakes. Bug: http://curl.haxx.se/mail/archive-2012-07/0013.html
Configuration files such as curl_config.h and all config-*.h no longer exist nor are generated/copied into 'src' directory, now these only exist in 'lib' directory from where curl tool sources uses them. Additionally old src/setup.h has been refactored into src/tool_setup.h which now pulls lib/setup.h The possibility of a makefile needing an include path adjustment exists.
