The pidfd_{open,poll}_test.c files both include `linux/wait.h` and later `sys/wait.h`. The former has `#define P_ALL 0`, but in the latter P_ALL is part of idtype_t enum, where it gets substituted due to the aforementioned define to be `0`, which then results in `typedef enum {0, ...`, which then results into a compiler error: "error: expected identifier before numeric constant". Since we need `sys/wait.h` for waitpid, drop `linux/wait.h`.

Sorry, I missed this patch. This is problematic and your patch would only temporarily fix it. If glibc adds a P_PIDFD to the enum we'll run into the same issue. So please: - remove the linux/wait.h header (as you've already done here) - add a custom define for P_PIDFD under a different name, e.g.: #ifndef __P_PIDFD #define __P_PIDFD 3 #endif and add a comment above it explaining the reason for this mess.
Thanks and (_ugh_) Christian
