newlib: Compiler gets confused when building 32-bit compatibility

Question

I am compiling newlib so I can continue the building of my cross-compiler, but newlib is getting confused with the 32-bit support I also included in my cross-compiler.

I already have my cross-compiler compiled and installed, but it's missing a standard library along with libgcc, so most programs will not compile, but programs not using standard functions will compile as long as the -nostdlib argument is used

If you're asking to me: "You should use glibc instead!", I'll answer: It requires source files from Linux, but the Linux source code does not play well on Windows, because Windows thinks that some files are the same due to the case-insensitive file system.

The errors are:

Here's the entire log:

Original (some parts are in Spanish)
English translation

My compiler is: MinGW-w64 x86-64 (from MSYS2)
The cross-compiler I am trying to build is: Linux x86-64

Answer 1

I fixed it. I simply disabled multilib, because I can just simply build another compiler for 32-bit.
