Modifying PATH makes it find the 64-bit compiler now. However, I'm
still getting the same issues with the compiler and linker flags:

ifort: command line warning #10006: ignoring unknown option '/shared'
ifort: command line warning #10006: ignoring unknown option '/shared'
ifort: command line warning #10006: ignoring unknown option '/LC:\Python27\libs'
ifort: command line warning #10006: ignoring unknown option
'/LC:\Python27\PCbuild\amd64'
ifort: command line warning #10006: ignoring unknown option '/lpython27'
ifort: command line warning #10006: ignoring unknown option '/OU'
ifort: command line warning #10006: ignoring unknown option '/OT'
ifort: command line warning #10155: ignoring option '/optimize';
argument required
ifort: command line warning #10006: ignoring unknown option '/O.'
ifort: command line warning #10006: ignoring unknown option '/O\'
ifort: command line warning #10006: ignoring unknown option '/Of'
ifort: command line warning #10006: ignoring unknown option '/Oo'
ifort: command line warning #10006: ignoring unknown option '/Oo'
ifort: command line warning #10006: ignoring unknown option '/O.'
ifort: command line remark #10010: option '/Op' is deprecated and will
be removed in a future release.
See '/help deprecated'
ifort: command line warning #10148: option '-Oy' not supported
