I've just got this error while building latest version of OpenSSL:
n_pkey.c
.\crypto\asn1\n_pkey.c(96) : error C2370: 'NETSCAPE_ENCRYPTED_PKEY_it' : redefinition; different storage class
.\crypto\asn1\n_pkey.c(93) : see declaration of 'NETSCAPE_ENCRYPTED_PKEY_it'
.\crypto\asn1\n_pkey.c(106) : error C2370: 'NETSCAPE_PKEY_it' : redefinition; different storage class
.\crypto\asn1\n_pkey.c(103) : see declaration of 'NETSCAPE_PKEY_it'
NMAKE : fatal error U1077: 'cl' : return code '0x2'
Stop.
What is it?
