unresolved external (___iob_func) with 1.0.1p using VS2015

[John Chow]

Hi,

I've been using 3noch's instructions for building OpenSSL 1.0.1 using Visual Studio here :
http://developer.covenanteyes.com/building-openssl-for-visual-studio/

These steps build fine for both VS2012 and VS2013 with 1.0.1p, but there is a link issue when using VS2015 (VC14). The last line of my output is:
                link /nologo /subsystem:console /opt:ref /debug /out:out32\constant_time_test.exe @C:\Users\John\AppData\Local\Temp\nmF77B.tmp
constant_time_test.obj : error LNK2019: unresolved external symbol ___iob_func referenced in function _main
out32\constant_time_test.exe : fatal error LNK1120: 1 unresolved externals

I've attached my complete output of nmake -f ms\nt.mak

Tested with 1.0.1p (and o). On Windows 8.1 64bit with VS2012, 2013 and 2015 (fail case).

/John
