Support `oop` Compilation For 32bit With GCC And MSVC

[taljacob2]

• For MSVC:

  • Edit build-lib.bat to compile with 32bit.
  • Edit release-msvc.bat:
    • Add oop32.lib to the final archive.

• For GCC:

  • Edit build-lib.sh to compile with 32bit.
  • Edit release-gcc.sh:
    • Add oop32.a to the final archive.

• gcc:
  • Add the -m32 for 32 bit.
  • Add the -m64 for 64 bit.

For using -m32 on a 64 bit machine, you must install the package of 32bit compiling, with:

sudo apt-get install build-essential libc6-dev-i386

and only then you can run -m32.

Or else, you may get the following errors (for example):

• fatal error: bits/libc-header-start.h: No such file or directory
     25 | #include <bits/libc-header-start.h>
  

• /nix/store/4pqv2mwdn88h7xvsm7a5zplrd8sxzvw0-glibc-2.35-163-dev/include/gnu/stubs.h:7:11: fatal error: gnu/stubs-32.h: No 
  such file or directory
      7 | # include <gnu/stubs-32.h>
        |           ^~~~~~~~~~~~~~~~
  compilation terminated.
