# libressl provides an OPENSSL_init_ssl, which causes configure to determine
# HAVE_OPENSSL_INIT_SSL is 1, but libressl does not define OPENSSL_INIT_SETTINGS,
# so the build ends up failing anyway.  libressl provides this signature:
#   int OPENSSL_init_ssl(uint64_t opts, const void *settings);
#
# I tried typedef'ing OPENSSL_INIT_SETTINGS to void:
#   sed -i '' -e '/#if HAVE_OPENSSL_INIT_SSL/a\
#   #define OPENSSL_INIT_SETTINGS void' sslcls.h
#   sed -i '' -e '/#if HAVE_OPENSSL_INIT_SSL/a\
#   #define OPENSSL_INIT_SETTINGS void' sslcls.c
#
# This allows socat to build, but still fails to link:
#   gcc -mcpu=970 -O2 -D_GNU_SOURCE -Wall -Wno-parentheses  -DHAVE_CONFIG_H -I. -I/opt/libressl-3.4.2/include -I/opt/readline-8.2/include  -L/opt/libressl-3.4.2/lib -L/opt/readline-8.2/lib  -o socat socat.o libxio.a -lwrap -lutil -lresolv  -lreadline  -lssl -lcrypto
#   Undefined symbols:
#     "_OPENSSL_INIT_new", referenced from:
#         __xioopen_openssl_prepare in libxio.a(xio-openssl.o)
#   ld: symbol(s) not found
#
# So instead we override config.h to say we don't have OPENSSL_init_ssl.
