This patch won't help, the error in question is a result of 
OpenSSL incorrect assembler handling in OpenSSL 1.0.2*.  In 
OpenSSL 1.* times OpenSSL folks did the following things:

- about 1.0.0 they changed default compilation procedure (the one 
  used by nginx on Windows), previously documented to be a way to 
  compile without asm at all, to use MASM; at the same time, they 
  declared that they will only support NASM.

- in 1.0.2 they broke both building with MASM (see errors 
  above) and building without asm at all (as per new compilation 
  procedure, introduced in 1.0.0).

Some comments about this can be found here (RT link seems to be 
dead for now):

Trivial workaround is to use latest OpenSSL from the 1.0.1 branch 
(1.0.1m as of now), it compiles fine either way.
