Describe the bug

The configure script packged in a tar.gz release file seems to be generated with old autoconf. This prevents proper stdbool.h detection and leads to the following build error on GCC 15:

In file included from autoopts/project.h:30,
                 from libopts.c:2:
./compat/compat.h:188:19: error: cannot use keyword ‘false’ as enumeration constant
  188 |    typedef enum { false = 0, true = 1 } _Bool;
      |                   ^~~~~

To Reproduce

Steps to reproduce the behavior:

1. download tcpreplay 4.5.1
2. invoke ./configure (check for stdbool.h detection messages)
3. invoke make

Expected behavior

stdbool.h is detected and the build is successful

System (please complete the following information):

• OS: Linux
• OS version: Rhino Linux 2025.1 all
• Tcpreplay Version: 4.5.1

Additional context

If I invoke autoreconf -i prior to ./configure, the stdbool.h is detected correctly.
