Godot: Cannot build Windows export template from MacOS

[rafaelgdp]

Godot version: Master Branch, Commit 781e4f8673857b2b318e919ecb780bfad972a5a6

OS/device including version: MacOS Mojave 10.14.6. Macbook Pro 15" 2018.

Issue description: I can build for MacOS normally. However, when I try to build an export template for Windows, there are some function calls that are not recognised. Searching the internet for the solution, some people argued that sprintf_s and wcspy_s are not functions from the standard C++ Library. Maybe other functions should be used instead.

Steps to reproduce: Install everything you need to compile Godot from source (i.e. Python, scons, etc). Additionally, I installed mingw with brew, as recommended by the docs (brew install mingw).

Minimal reproduction project: I do not have a project to share, as I'm simply trying to build Godot itself for Windows from a Mac machine.

Try adding CXXFLAGS="-DMINGW_HAS_SECURE_API" to the scons command, it's missing from the default configuration of some MinGW distribution.

Adding this flag actually solved my problem!! I have no idea what it stands for, but it made the build work! Thank you so much! By the way, I wonder if this notice should be present in the official documentation. It was really frustrating not being able to compile the engine because of silly "undefined-token" errors.

@rafaelgdp I opened a pull request on the documentation repository, see above :slightly_smiling_face:

This is just for posterity who ran into this issue,

As per https://github.com/godotengine/godot/issues/33062,
We embeded -DMINGW_HAS_SECURE_API=1 into the build script,
which means that people don't need to specify this flag manually.
We expect people not to see this error anymore on the latest 3.1 and master.
