Bug Description

A lot of deprecation warnings turned into errors when trying to build latest dub stable with latest ldc:

source/dub/dependency.d:917:32: error: scope variable 'this' assigned to non-scope parameter 'oth' calling 'opEquals' [-Werror=deprecated]
  917 |                 if (m_versA == m_versB)
      |                                ^
source/dub/dependency.d:920:44: error: scope variable 'this' assigned to non-scope parameter 'a' calling 'doCmp' [-Werror=deprecated]
  920 |                 return doCmp(m_inclusiveA, m_versA, v) &&
      |                                            ^
source/dub/dependency.d:921:48: error: scope variable 'this' assigned to non-scope parameter 'b' calling 'doCmp' [-Werror=deprecated]

      |                                                ^
source/dub/dependency.d:939:40: error: scope variable 'this' assigned to non-scope parameter 'oth' calling 'opEquals' [-Werror=deprecated]
  939 |                 return this.m_versA == this.m_versB;
      |                                        ^

How to reproduce?

• download https://github.com/dlang/dub/archive/v1.34.0.tar.gz
• DMD=ldmd2 GITVER=v1.34.0 ldc2 -run build.d

Expected Behavior

dub builds correctly despite the deprecation warnings and doesn't block downstream usage by enforcing every warning to be a fatal error

nevermind, apparently gdc was being installed and picked by accident, closing in favour of #2577
