1.6 suffers from the same issue:
{{{
...
cc -std=c99 -I -I -g -O2 -c ZmodF_mul.c -o ZmodF_mul.o
In file included from /usr/include/stdio.h:46,
from ZmodF_poly.h:40,
from ZmodF_mul.c:34:
/usr/include/sys/types.h:101: error: duplicate `unsigned'
make: *** [ZmodF_mul.o] Error 1
dima@SPMS-DIMA-W7 /tmp/flint-1.6
}}}
to get that far when compiling, I needed to remove quite a bit of
"error: redeclaration of `i' with no linkage" in QS/mp_linear_algebra.c
and QS/mp_sieve.c
E.g:
{{{
QS/mp_linear_algebra.c: In function `insert_lp_relation':
QS/mp_linear_algebra.c:334: error: redeclaration of `i' with no linkage
QS/mp_linear_algebra.c:329: error: previous declaration of `i' was here
}}}
the reason for that is rather than writing
{{{
for (unsigned long i = 0; ...
}}}
which restricts the scope of i to the for loop, you write
{{{
unsigned long i;
for (i = 0; ...
}}}
there, in many places. Well, maybe some weird compiler can accept this,
but gcc does not...
