silence -Wpedantic by removing extra ';'
Fix unused value (reported by scan-build)
Check emptiness rather than size greater than zero
Style changes for readability
Remove unused and broken implementation of flag and frontier styles.
Fixed a bug in the last commit and silenced more warnings.

rgbcolor is now graphic_color.
Small fixes for compiling with gcc47.
reenable build for cmake-2.8.11 - for Saucy
provide alternative for target_link_directories cmake functions for precise
reduce cmake requirement for precise
