Git build failure: v2.47.0 on Solaris 10 SPARC64

Hi,

Reporting a build failure on version 2.47.0 of git, grabbed from the official sources. Our environment is:

Compiler: gcc (GCC) 9.5.0

Linker: GNU ld (GNU Binutils) 2.43

Target machine triplet: SPARC64-SUN-SOLARIS2.10

Target machine hardware: Sun Blade 150 UltraSPARC IIe workstation

Target OS: SunOS 5.10 Generic_150400-59 sparc SUNW,Sun-Blade-100 Solaris Sun Microsystems SunOS 5.10 Generic_150400-59 PATCH January 2018

After running ./configure, which succeeds, running `make all` gives:

root@iris:/usr/src/depot/progress/git-2.47.0# make all
     CC daemon.o
In file included from daemon.c:3:
git-compat-util.h:1012:13: error: conflicting types for 'inet_ntop'

Anyone know what's going on here?
