Building x32 libraries on x64 windows machine

[Neil Horman]

This error:
fatal error LNK1112: module machine type 'x64' conflicts with target
machine type 'x86'

says that you're set up for using x64 native tools, despite indicating you
have opened the x86 native tool command

Try running
vcvarsall.bat x32

Which should force your environment to build in 32 bit mode

Its also possible that you need to run make distclean again.  If you had
leftover 64 bit objects in your tree, this error would be the result
