When building OpenSSL 1.0.1e in the context of a larger build, the build fails
with the following error:
perl crypto\bn\asm\x86_64-gf2m.pl tmp32dll\x86_64-gf2m.asm
ml64 /c /Cp /Cx /Zi /Fotmp32dll\x86_64-gf2m.obj tmp32dll\x86_64-gf2m.asm
Assembling: tmp32dll\x86_64-gf2m.asm
tmp32dll\x86_64-gf2m.asm(1) : error A2088: END directive required at end of file
Microsoft (R) Macro Assembler (x64) Version 8.00.50727.762

NMAKE : fatal error U1077: '"C:\Program Files (x86)\Microsoft Visual Studio
8\VC\BIN\x86_amd64\ml64.EXE"' : return code '0x1'
Stop.
The build finishes successfuly when nmake is invoked again. The failure is much
less probable in stand-alone OpenSSL builds.
Used software:
* Windows 7 Professional SP1, 64 bit
* Microsoft Visual Studio 2010 10.0.40219.1 SP1Rel command prompt
(vcvarsall.bat amd64)
* Perl v5.16.2, Binary build 1602 [296513] provided by ActiveState

I think that the proper solution would be to use temporary files instead of
pipes when generating ASM on Windows.
Note that the bug is similar to bug #2817 but the workaround described in the
bug (disable STDOUT buffering) does not work for me.
