A special section number (-2) marks symbolic debugging symbols,
including structure/union/enumeration tag names, typedefs, and
the name of the file. A section number of -1 indicates that the
symbol has a value but is not relocatable. Examples of
absolute-valued symbols include automatic and register variables,
function arguments, and .eos symbols.
But from Ian Lance Taylor:
http://sources.redhat.com/ml/binutils/2000-08/msg00202.html
the actual tools all marked them as section -1. So the GNU COFF
assembler follows historical COFF assemblers.
However, it causes problems for djgpp
http://sources.redhat.com/ml/binutils/2000-08/msg00210.html
By defining STRICTCOFF, a COFF port can make the assembler to
follow the documented behavior. */
