[PD] the "config-pd-msvc.txt" file

I apology for a such newbee's question but there is some points in the config-pd-msvc.txt that I do not understand :

I have fill the path: # where is PD?
# where should flext libraries be built?

and comment out : # where is MS VC++? # where is the pthreads package? # where is the SndObj directory? #SNDOBJ=f:\prog\audio\sndobj # where is the STK include directory? # where should flext libraries be installed?

I do not understand the following lines and it should be a problem because I use MSVC6, by default I also put it in comment. # user-definable compiler flags # e.g. FLEXT_USE_SIMD enables SIMD support for capable CPUs (for MSVC6, you need the Processor Pack) #UFLAGS=/DFLEXT_USE_SIMD /G6 /arch:SSE

Actually when I run "build-pd-msvc.bat" a folder "s" is create in the specifiied folder it is empty and I obtain this text in cmd:

    C:\gabriel\flext>C:\gabriel\flext\build-pd-msvc.bat
