This may be the same sort of bug I saw in MPFR a few weeks ago

conftest.c:2:10: error: a function declaration without a prototype is 
deprecated in all versions of C [-Werror,-Wstrict-prototypes]
int main () { return 0; }
1 error generated.
configure:5985: $? = 1
failed program was:

int main () { return 0; }
configure:7072: result: no
configure:7310: error: could not find a working compiler, see config.log 
for details

This is seen on FreeBSD 14.0 on a RISC-V machine ( the SiFive board )
however I bet it happens just about anywhere if one goes with strict
