Publish GCC 'specs' customization HOWTO. * gccspecs.html: New file; adapted from original Drupal content, and in particular, on user comments relating to that content, this offers advice on customizing GCC's default behaviour, especially insofar as it affects include file and library search paths, and the option to deploy non-free Microsoft C runtime libraries, as alternatives to pseudo-free MSVCRT.DLL.
Specify some additional site style properties. * site.css (h4): Set margins globally. (page-view): Set minimum relative display width. (dl.masthead): No longer required; delete specification. (div.overlapped) [following "masthead"]: Adjust top margin. (nowrap, box-out, table.borderless): New styling classes. (pre.vt) [box-out]: Specialization of <code> style, for use in illustration of screen display output; lighten text colour. (kbd) [pre.vt]: Darken text colour, for keyboard input. (code) [within <a> tag scope]: Inherit text colour. (code) [within body text]: Lighten text colour.
