I'm afraid the problem is more that pkgsrc can't magically uncomment lines.

lang/gcc6/buildlink3.mk:

# Packages that link against shared libraries need a full dependency.
#.if defined(_USE_GCC_SHLIB)
#DEPENDS+=      {gcc6, gcc6-libs}>=${_GCC_REQD}:../../lang/gcc6-libs
#ABI_DEPENDS+=  {gcc6,gcc6-libs}>=6.0:../../lang/gcc6-libs
#.endif

while lang/gcc48/buildlink3 has:

# Packages that link against shared libraries need a full dependency.
.if defined(_USE_GCC_SHLIB)
DEPENDS+=       {gcc48,gcc48-libs}>=4.8:../../lang/gcc48-libs
ABI_DEPENDS+=   {gcc48,gcc48-libs}>=4.8.0:../../lang/gcc48-libs
.endif

(gcc49 is OK too, 5/7 have it commented out)

Hm, so GCC 5, 6 and 7 are -- err -- not fully supported yet? I wouldn't 
care too much if 4.8, 4.9 or 5 wouldn't error out on std::to_string(0).
