The following two files represent two ways to convert string to double considering locale.

• strtod_fast.c uses standard C runtime function
• strtod_slow.c uses a hand written implementation

I experiment the code on 3 compilers

1. MinGW-UCRT in msys2

$ gcc -v

According to this issue JuliaPy/PyCall.jl#665, we should call PyCall.fixqtpath() before plt.plot()
