# NOTE: BetterC flag
#       We explicitly specify the betterC flag to support older DUB releases
#       Like v0.9.24

# NOTE: GDC 5.4
#       Doesn't work, ld whines about missing _tlsstart/_tlsend (TLS) references
#       value for C++/ObjC but not D:
#         -fno-rtti
#         -fno-weak
#         -fno-threadsafe-statics
#         -fextern-tls-init
#       -fno-switch-errors: not a command-line option
#       -nophoboslib: makes the linker complain more
#       Tried with "-fno-moduleinfo" "-fno-emit-moduleinfo"

# NOTE: GDC and betterC
#       Currently (even with GDC 10.3), when compiled with -fno-druntime
#       (similar to -betterC), the linker will whine about an undefined reference
#       to __gdc_personality_v0, because the gdc-druntime defines this reference.
#       Glibc (and subsequently, GCC) has a similiar function,
#       __gcc_personality_v0, that is served when unwinding the stack, so to
#       handle exceptions.

# NOTE: GDC 11.1 and betterC
#       Yes, it works with -fno-druntime, so it can be possible to add
#       -gdc-betterc build types in the future.

# NOTE: Configurations and Sub-Packages
#       Sub-packages do not take build type options from root dub file.
#       But since configurations do, they are defined here, this is important
#       because on the reliance on betterC.

# NOTE: Documentation (docs/ddox) builds
#       Works best with the "library" configuration (-c|--configuration)

# ANCHOR Integration tests

# NOTE: These MUST be ran as "dub test -b TEST"
# NOTE: Dedicated tests must only exist if one of these conditions are met
#       - Requires user input (e.g., readline)
#       - Are prone to crashing application (e.g., longjmp on Windows)
