dub 1.2.0 building a project using dmd 2.073.0 puts out the following warnings on x86_64 Linux.
This seems not to be project specific. It occurs building a working project that previously had no such warnings and has not been changed since when that was so, both before and after dub upgrade and dub --force.
## Warning for package libasync, configuration 32mscoff ##
The following compiler flags have been specified in the package description file. They are handled by DUB and direct use in packages is discouraged. Alternatively, you can set the DFLAGS environment variable to pass custom flags to the compiler, or use one of the suggestions below:
-m32mscoff: Use --arch=x86/--arch=x86_64/--arch=x86_mscoff to specify the target architecture
I get this several times for libasync and memutils, more than once each.
Should I be concerned?
