I made to compile a bunch of libs on Win64 and got my D project

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?
You should not need to link manually against msvcrt, dmd does
this for you. You can view the linker commands that are stored
inside a object file via microsoft dumpbin tool "dumpbin
/DIRECTIVES your.obj".
You should check the declarations of the functions that cause a
unresolved external error. If they have a "export" in front of
them, remove the export. I can not think of any other reason why
dmd would otherwise reference a import symbol. Import symbols are
symbols used for dll linking and start with "__imp_"
Out of curiosity, why do you pass "-m64" 6 times to dmd? Once
would be enough.
For debug builds targeting windows 64 I would also highly
recommend using "-gc -op" instead of "-g". This will give a much
better debugging experience in Visual Studio.
