clang-cl compile error in 'cipher_rc4_hmac_md5_hw.c'

[gvanem]

Compiling from today's git master and using clang-cl ver. 16.0.0, causes this error:

providers/implementations/ciphers/cipher_rc4_hmac_md5_hw.c(80,13):
  error: call to undeclared function 'rc4_md5_enc'; ISO C99 and later do not support implicit function declarations 
  [-Wimplicit-function-declaration]
            rc4_md5_enc(ks, in + rc4_off, out + rc4_off,
            ^

            rc4_md5_enc(ks, in + rc4_off, out + rc4_off,
            ^
2 errors generated.

Adding a -Wno-implicit-function-declaration to my CFLAGS fixes it.
But there should IMHO be a prototype for this function somewhere. It's now-where AFAICS.

I am really curious how you could trigger this code to be compiled in as the build.info currently does not set the RC4_ASM define when building libcrypto or liblegacy.

Could you show me more of the build log? In particular the clang invocation?

[gvanem]

Doesn't enable-asm add -DRC4_ASM?

[t8m]

No, it doesn't.
