Not sure what to do about this. compiler/src/dmd/link.d adds this switch, as it is necessary in order for druntime/src/importc.h to do its job.

GCC: Put a note into the documentation that this switch is used and that a certain GCC version is required. It is in GCC since 2008 [1], but I could not find the exact GCC version number.

How is the problem solved with other compilers (clang, msvc)?
