cairo(D) / x64 / unresolved externals / don't know why

[Robert M. Münch via Digitalmars-d-learn]

I made to compile a bunch of libs on Win64 and got my D project 
compiled as well. Only problem left are some strange unresolved 
externals.

cairo-static.lib(cairo-image-source.obj) : error LNK2001: unresolved 
external "__imp__hypot"

and some more missing in other .obj files:

"__imp__ctime64"
"__imp_ldiv"
"__imp_strncpy"
"__imp_rand"

IMO this all looks like msvcrt standard lib stuff so wondering why it's 
not found. Do I explicitly have to link to the msvcrt lib?
