I am trying to run QT5 configure. It exits right away in TCC, but works in CMD. It doesn't matter if I set "repeat CMD bugs", the result is the same. Are there any options in TCC to make it really compatible? It comes to this line in configure.bat:
The directory qtbase exists, so CMD continues, because || refers to the mkdir result. It seems like TCC instead evaluates `if`, thinks that || is about `if`'s result and exits.
if not exist qtbase mkdir qtbase || exit /b 1
