static declaration of ‘fmpz_ui_pow_ui’ follows non-static declaration

[tillea]

Hi,
when building arb with gcc-13 an issue is uncovered that was reported in a Debian bug report. As you can see there the build fails with

gcc -fPIC -Wdate-time -D_FORTIFY_SOURCE=2 -g -O2 -ffile-prefix-map=/<<PKGBUILDDIR>>=. -fstack-protector-strong -fstack-clash-protection -Wformat -Werror=format-security -fcf-protection -I/<<PKGBUILDDIR>> -I/usr/local/  include -I/usr/local/include -I/usr/include -c add_si.c -o ../build/fmpr/add_si.lo -MMD -MP -MF "../build/fmpr/add_si.d" -MT "../build/fmpr/add_si.d" -MT "../build/fmpr/add_si.lo"

Kind regards, Andreas.

Arb has been merged with flint 3.0; the standalone arb library is not compatible with flint 3.0.

Debian should remove the separate flint-arb package once it has upgraded flint to 3.0.
