Thanks for the tip Ian. In that routine one could easily ignore a
leading ".". In abstract one might want to handle "." inside the
name, or translate characters (such as "$") allowed in ELF symbols but
not in C (or in some other language), whereby a simple concept starts
to get out of hand; thus:
- Could we assume that standard ELF section names can be mapped to C
identifiers just by mapping the leading "."?
- What mapping would you suggest? If the leading "." is dropped then
the resulting would collide with a common name (text or data in
particular). This problem seems unsolvable in general, so should one
make an effort at all (mapping "." to a single underscore for
