> 
> As previously announced, DPDK 23.11 will require a C11 supporting
> compiler and will use the C11 standard in all builds.
> 
> Forcing use of the C standard, rather than the standard with
> GNU extensions, means that some posix definitions which are not in
> the C standard are unavailable by default. We fix this by ensuring
> the correct defines or cflags are passed to the components that
> need them.

> V5:
> * Fix build issues with bool type in altivec code, due to bool type
>   being in C11. Use __bool for altivec-specific version instead.
> 
> V4:
> * pass cflags to the structure and definition checks in mlx* drivers
>   to ensure posix definitions - as well as C-standard ones - are
>   available.
> 
> V3:
> * remove (now unneeded) use of -std=gnu99 in failsafe net driver.
> 
> V2:
> * Resubmit now that 23.11-rc0 patch applied
> * Add _POSIX_C_SOURCE macro to eal_common_errno.c to get POSIX
>   definition of strerror_r() with c11 standard.
