   4 Subject: Support POSIX basename() from musl libc
   5
   6 Musl libc 1.2.5 removed the definition of the basename() function from
   7 string.h and only provides it in libgen.h as the POSIX standard
   8 defines it.
   9
  10 This change fixes compilation with musl libc 1.2.5.

  21 basename() modifies the input string, copy it first with strdup(), If
  22 strdup() returns NULL the code will handle it.
