Re: mbedtls warning "implicit declaration of function 'time'"
Figured out the problem. This is a multi-layered issue that starts with an invalid Kconfig setting I did. I had, by default, turned on MBEDTLS in the SOC Kconfig. This had a ripple affect:

Subject: [Zephyr-users] mbedtls warning "implicit declaration of function 'time'"
I’m having some weirdness with building the mbedtls module giving me a compiler warning related to “time”:
/home/dleach/work/zephyrproject/modules/crypto/mbedtls/include/mbedtls/platform_time.h:74:24: warning: implicit declaration of function 'time'; did you mean 'gmtime'? [-Wimplicit-function-declaration]
#define mbedtls_time time
/home/dleach/work/zephyrproject/modules/crypto/mbedtls/library/ssl_cli.c:697:9: note: in expansion of macro 'mbedtls_time'
t = mbedtls_time( NULL );
The warning is coming from my PR #17736 for /tests/lib/fdtable/. What is confusing me is that using similar configurations for /tests/crypto/rand32, which builds the same file, doesn’t get the warnings. Generally speaking the mbedtls stuff is an optional configuration between mbedtls and tinycrypt but for the KW41Z I have it generically turned mbedtls on.
I can also get the warning to go away for the fdtable test if I enable “CONFIG_NEW_LIBC”.
