#733 Compilation error with clang 4.0 / sincos

[Thierry Thomas]

Hello,
Trying to compile GDL v. 0.9.8 on FreeBSD 11.1 (with clang 4.0), it produces the following error:

In file included from /wrkdirs/usr/ports/science/gnudatalanguage/work/gdl-0.9.8/src/triangulation.cpp:27:
/wrkdirs/usr/ports/science/gnudatalanguage/work/gdl-0.9.8/src/ssrfpack.c:2584:1: error: use of undeclared identifier 'sincos'
sincos (*plat, &p[2], &cos_plat);    sincos (*plon, &p[1], &p[0]);    p[0] *= cos_plat;    p[1] *= cos_plat;
^
/wrkdirs/usr/ports/science/gnudatalanguage/work/gdl-0.9.8/src/ssrfpack.c:2584:38: error: use of undeclared identifier 'sincos'
sincos (*plat, &p[2], &cos_plat);    sincos (*plon, &p[1], &p[0]);    p[0] *= cos_plat;    p[1] *= cos_plat;

With clang 5.0, everything is OK.
