I'm not sure why that would have stopped working, but the way to use a
.bat from a .bat is to 'call' it:

call 36\PCbuild\build.bat -e -d

.bat scripts don't care about the exit codes of what they run, errors
must be explicitly checked and 'exit' called if you want the script to
die early.  Try this for an unconditional build on all three branches,
with a report at the end if any of them failed:

call 36\PCbuild\build.bat -e -d
set rc36=%ERRORLEVEL%

call 35\PCbuild\build.bat -e -d
set rc35=%ERRORLEVEL%

call 27\PCbuild\build.bat -e -d
set rc27=%ERRORLEVEL%

@if %rc36% NEQ 0 (
    echo 3.6 build failed, rc: %rc36%
)
@if %rc35% NEQ 0 (
    echo 3.5 build failed, rc: %rc35%
)
@if %rc27% NEQ 0 (
    echo 2.7 build failed, rc: %rc27%
)
