Related to #3449.

The following files must be inspected.

• asm.c (no impact)
• dts.c (no impact)
• c.c (removed)
• ./cxx/cxx_parser_tokenizer.c (fixed in c-based: fix to handle edge case #3796)
• cpreprocessor.c
• ldscript.c (fixed in LdScript: reject " and ' as a part of an identifier #3782)
• protobuf.c (no impact)
• vera.c (fixed in Vera: revise the dataflow of cppGetc -> vStringPut #3886)
• c-based.c (fixed in c-based: fix to handle edge case #3796)

This may be a chance toremove c.c that includes OldC and OldC++.

A fix can be:
