There is an implicit function declaration in provider_conf_init, currently resulting in a warning during the build:

crypto/provider_conf.c: In function 'provider_conf_init':
crypto/provider_conf.c:329:13: warning: implicit declaration of function 'EVP_default_properties_enable_fips' [-Wimplicit-function-declaration]
  329 |         if (EVP_default_properties_enable_fips(libctx, 1) != 1)
      |             ^~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~

Probably you just need to add

#include <openssl/evp.h>

to the top of the file, or add a suitable declaration of EVP_default_properties_enable_fips.

I'd appreciate if you could fix this following your patch management practices, otherwise I'll just pile on another patch for this.
