sharutils: fix build with gcc-15.0.1

* gcc-15 uses gnu23 standard for c:
  https://gcc.gnu.org/git/?p=gcc.git;a=commitdiff;h=55e3bd376b2214e200fa76d12b67ff259b06c212
  bool is included as a reserved word, causing an error due to duplicate declaration.

  Also, when parameters are empty, an error occurs. Therefore, when using
  functions from the standard library, modify the defines in configure.ac
  and source code to use standard library functions.
