[Lynx-dev] [PATCH] compile with OpenSSL 1.1.0b; WWW/Library/Implementation/HTTP.c

[Taketo Kabe]

I tried to compile Lynx 2.8.8rel2 with latest OpenSSL 1.1.0b, but failed with
>> ../../../WWW/Library/Implementation/HTTP.c:723: dereferencing pointer to 
>> incomplete type

The code tries to access the opaque pointer->options, which seems the
last part left of directly accessing the struct member.
Patch below fixed it.

lynx2.8.9dev.9 seems to emit same error.
In 2.8.9dev9, configure relies heavily on
POSIX shell's "case" syntax, so it wasn't practical in my environment;
dash(1) seems essential contrary to autoconf's philosophy.
