Shouldn't these two statements be in the project's stdafx.h file?

Extending the namespace std - cppreference.com[^]:

It is undefined behavior to add declarations or definitions to namespace std or to any namespace nested within std, with a few exceptions noted below

I am sorry you went thru all this , but the issue is not in compiling.
The code just need those "redefinitions" to work, it compiles fine.

1. Running the preprocessor
   
2. Compiling the intermediate file created by the preprocessing to assembly code
   
3. Creating object files from the assembly code files
   

# Run the preprocessor and stop 
# The result is printed to stdout and redirected to a file
gcc -E example.c > example.i

# Compile passing the intermediate file and stop
# Creates assembly code file example.s
gcc -S example.i

# Compile passing the assembly code file and stop (do not link)
# Creates object file example.o
gcc -c example.s

gcc -save-temps -c example.c
