* Opt into POSIX functions with `_POSIX_C_SOURCE` before any system headers are `#include`d * Allow user to override `make develop`'s `WARNFLAGS` and `CXXFLAGS` * Use `make develop` on 32-bit Cygwin with sanitizers disabled * Do not unnecessarily redefine `fseek` and `ftell` * Disable a false-positive `-Wno-null-dereference` on 32-bit Cygwin Co-authored-by: ISSOtm <[email protected]>
