'timespec': 'struct' type redefinition error when compile in VS2019/17

[VadymKargin]

Hi,

I tried to compile this in VS2019 and 2017 and it gives following error:
error C2011: 'timespec': 'struct' type redefinition

Do we have to add
#define HAVE_STRUCT_TIMESPEC
in pthread.h with a condition for VS builds?

Thanks

You can add #define HAVE_STRUCT_TIMESPEC to include file <pthread.h>

With VS 2019, the following lines are no longer needed:

pthread.h : l.318-324

#if !defined(_TIMESPEC_DEFINED)
#define _TIMESPEC_DEFINED
struct timespec {
time_t tv_sec;
long tv_nsec;
};
#endif /* _TIMESPEC_DEFINED */

Indeed, with VS2019, time_spec is already defined like this.
It would be interesting to change these lines (delete them or add a condition "if the VS redist is 2017 or more").

I took out line 318-324 and I still have problem compiling. Now I have LNK2019 error afterward. What can I do to fix this? I'm using VS2022 not sure if it'd make a different.

Building such things always painful on Windows.
