If the standard allow the compiler to read header files we did not ask
for, then we are stuck.

This is unrelated. I am surprised there not more like this.

Cheers,
Bill.

There're actually more like that, I just gave one as an example. Any chance of fixing it?

Thanks,

Actually, this one is more pressing - happens with the stock g++ compiler:

g++ -c -I. -I../src/headers -fPIC -O3 -Wall -fno-strict-aliasing -fomit-frame-pointer -o arith1.o ../src/basemath/arith1.c

../src/basemath/arith1.c: In function ‘long int* qfi_Shanks(GEN, GEN, long int)’:

../src/basemath/arith1.c:4591:16: error: call of overloaded ‘sqrt(long int&)’ is ambiguous

rt_n = sqrt(n);

../src/basemath/arith1.c:4591:16: note: candidates are:
