The code (both alt and entry) no longer assumes that the source code
filename is the same as the running program with '.c' added. Instead it
uses __FILE__. This does make it slightly less obscure (see next part)
but it is also slightly less error prone at least in some cases. The way
it worked before is that it copied to a buffer '*argv' and then used
strcat(3) with the string ".c" to come up with the filename. The author
actually stated:
As long as the source is in the same directory as the executable it
should be able to find it.
... but this was not strictly true. Now as long as the source file it
was compiled as is in the directory it will find it even if the
executable was copied/linked/renamed to something else.
Format/typo check README.md file.
