Your project.  You can do whatever you want.

I find it handy when debugging stuff and as a convenient way to switch between 
NMEA and whatever binary mode the device supports.  What do you use?

It's an up to date Alpine Linux which uses musl.  I keep a copy around to help 
uncover problems like this.  I'm pretty sure previous versions of gpsd built 
without errors on this system.

/usr/lib/libc.so -> ../../lib/ld-musl-x86_64.so.1

_GNU_SOURCE is set in gpsd_config.h

SConscript says:
    if config.env['target_platform'].startswith('linux'):     
...
        # for strnlen() and struct ifreq                           
        # glibc before 2.10, deprecated in 2.10+                     
        confdefs.append('#if !defined(_GNU_SOURCE)')                  
        confdefs.append('#define _GNU_SOURCE 1')
        confdefs.append('#endif\n')

Different system than above.

This happens on 32 bit Debian and 32 bit NetBSD.

gcc (Debian 10.2.1-6) 10.2.1 20210110
/usr/lib/i386-linux-gnu/libc.so.6 -> libc-2.31.so

gcc (nb4 20200810) 7.5.0
/lib/libc.so.12 -> libc.so.12.213
