D - not using phobos

If I have a different implementation of a phobos function (getch) inside a
.lib file, but I have neither the .obj nor the source code, how can I use
this function instead of that in phobos? dmd just seems to ignore it. I
tried compiling and linking in different stages, but it didn't work either.
Probably getch is part of the C RTL instead of phobos. Anyway, how can I use
a different one?

I can only assume that you talk about two functions that look for the
linker like two C functions in different .obj modules of different libraries.

I think there is no way to resolve this. The linker will take the first
getch he finds. This may depend on the order the libraries are searched. 
If the getch is bundled with other functions, it may be drawn in depending
on their usage. When the first getch() is found and included, the linker
will typically look further. Some linker may warn about "duplicate symbols"
while others won't.

Link your different one in first.

I could get the .obj and then .asm of that getch function. Now, I don't know
anything about assembler, so can somebody explain how I can make this work
with DMD? (getch.asm generated by obj2asm attached)

I don't understand what you're asking. If the .obj file you have should take
priority, put it first on the linker command. If it is still pulling in the
phobos version, I suspect the names are different.

The names are the same. What I don't understand is the "put first" thing,
because I even tried putting it (the obj) before my actual d code, but it
still didn't work.

As I said, you are up to the mercy of the linker(s). 
It's a "good old C rule" to not rely on that.

If you happen to be lucky you can remove to offending .obj from the library 
using some lib tool (any has options to add/del/extract .obj files) which 
effectively prevents its use. If it is bundled with other functions in an
.obj then you may be out of luck.

dmc a.obj b.obj

a.obj is first to the linker.
