Multiple issues using Emscripten to set up web client

[BeastFable]

I've freshly installed Emscripten and Make on a Mac, and I'm seeing many errors running the makefile:

src/surface.c:145:5: error: call to undeclared function 'surface_gl_new'; ISO
      C99 and later do not support implicit function declarations
      [-Wimplicit-function-declaration]
  145 |     surface_gl_new(surface, width, height, limit, mud);
      |     ^
1 error generated.
make: *** [src/surface.o] Error 1

src/surface.c is missing an #include "surface-gl.c" line at the top. So I added it to my local project.

emcc: error: MIN_FIREFOX_VERSION older than 68 is not supported
make: *** [mudclient.html] Error 1

Makefile references 52 as the minimum Firefox version, so I changed it to 68.

wasm-ld: error: too many errors emitted, stopping now (use -error-limit=0 to see all errors)

This one I'm not sure how to fix, because it looks like I can't edit those .o files in a text editor. At this point I'm thinking I have a massively different version of something and it's more strict than whatever you guys are running on macOS.

macOS version Tahoe (26.2), latest version of Emscripten SDK from Git, Make version 4.2.3 macos universal

Looks like these issues are happening on Windows as well, I'm stuck at the duplicate symbol part..

All of these issues are now fixed by the PR I have submitted: #249

• call to undeclared function 'surface_gl_new' - fixed by adding surface_gl_new declaration in surface.h
• MIN_FIREFOX_VERSION older than 68 is not supported - fixed by changing MIN_FIREFOX_VERSION to 68
• duplicate symbol: surface_gl_new - no change in PR, it was a faulty #include statement that my PR initially added
