Comment (by nickm):
This may be a debian-only issue: I have just noticed that apparently my
fedora desktop also claims to have GCC 9.2.1, but compilation is passing.
Apparently this happens because -Wextra-semi is detected as unsupported in
the autoconf script:
{{{
configure:18768: checking whether the compiler accepts -Wextra-semi
configure:18787: gcc -c -g -O2 -U_FORTIFY_SOURCE -D_FORTIFY_SOURCE=2
-fstack-protector-all -Wstack-protector --param ssp-buffer-size=1 -fPIE
-fasynchronous-unwind-tables -Wall -fno-strict-aliasing -Waddress -Warray-
bounds -Wdate-time -Wdouble-promotion -Wduplicate-decl-specifier
-Wduplicated-cond -Wextra -pedantic -Werror -Wextra-semi conftest.c >&5
cc1: error: command line option '-Wextra-semi' is valid for C++/ObjC++ but
not for C [-Werror]
cc1: all warnings being treated as errors
}}}
