# it is necessary to compile our own code with -fstack-protector to avoid undefined symbols

# at link time.

|
# Note that specifying -fstack-protector-strong or -fstack-protector-all will lead
|
|
# to a dependency on libssp-0.dll (at least when using the MinGW compilers from Debian),
|
|
# and there seems to be no easy way of linking it statically.
|

# Also note that adding this flag is not necessary when building from MSYS2 shell.

# Maybe revisit this once our runners are upgraded to Debian “Bookworm” 12.
