/* Start a function in its own named and numbered section, so that it
can be subject to linker garbage collection.
The linker links all .crt_* sections in asciibetical order at the same place.
So, the four digits in .crt_NNNN_xxx name are used to enforce link-time
ordering of the sections. Make sure to keep them in sequential order. The
first two digits are set in the files, the second two allow users to insert
code between our standard code fragments.
Note - the construction of the symbol names is critical - they need to match
the unresolved symbol references created by the compiler and assembler. */
