sokol/sounds examples in V repo cannot be compiled with tcc-amd64

[SleepyRoy]

I have a vague impression that compilation used to be successful X months ago.

vlang/v#8639 :)

[SleepyRoy]

I applied changes there, but some sokol/sounds examples still couldn't be compiled. Also I think v -cc tcc build-examples should be added to CI tcc-win. Have you ever tried it on your windows?

[spaceface777]

Have you updated your local tcc installation? I pushed a commit yesterday; run .\make.bat -tcc to update it.

[SleepyRoy]

Yep I was using latest tcc branch. For example v -cc tcc melody.v gave very long errors and here're some parts.

builder error:
==================
C error. This should never happen.

I found it quite strange because it was somehow using mingw64. So I wanted to "hide" my mingw64 and renamed it. Then I simply got

C compilation failed.
builder error: exec failed (CreateProcess) with code 2: 系统找不到指定的文件。(Translation: couldn't find intended files)
 cmd: gcc "@C:\Users\Roy\AppData\Local\Temp\v\melody.14326360450439642725.tmp.c.rsp"

still had strange relation with gcc.

This issue only applies to sokol/sounds examples, not all sokol examples.

[SleepyRoy]

BTW v -cc gcc sokol/sounds examples just worked nicely.

[spaceface777]

could you try again? I've pushed another fix.

[SleepyRoy]

Good work! It's fixed.
