D doesn't allow this, but C has two different namespaces for function/variable/typedef symbol names and tags for struct/union/enum. This blocks quite a number of the standard library functions from being compilable. --- struct sigaction { int sa_flags; }; extern int sigaction(struct sigaction *);

An attempt to fix this issue was done in: https://github.com/dlang/dmd/pull/12567 However this was reverted as was found to cause more issues.

This has been fixed. The C code works, but D can only see the function name. Not planning on fixing this for now.
