Akankshu,
CFLAGS is usually the flags you pass to gcc (or in this case ncc). It
simply is a lit of command line parameters that you pass to the
program. To see what various flags do, you should look at the man pages
for gcc/ncc. In general, the flag -D<SOMETHING> it basically is the
same as if you had typed #define <SOMETHING> in your code.
-D<SOMETHING>=### it's the same as #define <SOMETHING> ###.

Hi Paul
I dont have a similar problem but I want to learn about using CFLAGS
and PLFAGS in tinyoy-2.x. I have used some of them when people have
told me and for the most part they have worked but I want to learn
about the usage and different such flags ?
I look forward to hearing from someone

I am not aware of many people that are still using tinyos 1.x, so
I doubt you will be able to get any sort of authoritative response
from anyone. Since the compiler is complaining about
TOSH_NUM_NODES, have you considered adding to your Makefile a line
like this:
CFLAGS += -DTOSH_NUM_NODES=###
where ### is the number of nodes in your experiment. Most likely
something is referring to this #define and since it's not defined,
it's giving an error. Look at the file indicated:
/opt/tinyos-1.x/tos/platform/pc/nido.h:63
To see what the issue is.

I'm currently following the Lesson 5 (TOSSIM) from the TinyOS 1.x
Tutorial,
in which I'm supposed to compile CntToLedsAndRfm application. In that step i
found problems running the "make pc", and I realized that it happens for
other applications. It shows:

Someone on the mailing list suggested to add the flag
-fnesc-nido-tosnodes=1000 on the .target file found in
/opt/tinyos-1.x/tools/make, but the flags are there, and as it is seen in
the output above, they appear in the ncc command...
So, i don't know if I missed make, or if there are any other files of TinyOS
2.x that conflict with the 1.x version... How to fix this error?
My environment is the xubuntos distribution, running it's image in VMWare
Player.
I crucially appreciate all the help. Thanks in advance!
