[Rd] Problem with Makefile.win and environment variable

[Prof Brian Ripley]

> cl /Ic:\root/include /MT /EHsc /Ox /D "MSVC" /D "WIN32" /c TMLMath.cxx

will AFAIK not work when passed to the shell used (which is ash), and in 
any case will not work for paths with spaces in.

You still haven't shown us the Makefile.win, but probably you need

cl /I"${ROOTSYS}/include" /MT /EHsc /Ox /D MSVC /D WIN32 /c TMLMath.cxx
