Hi,

I have build tool chain using crosstool-ng 1.90.  I don't know much
about internals of tool chain. Can you please clear my doubts:

I guess you are referring to gcc's 'specs'

1. Where is built-in specs located?

It's built-in into gcc - Hence the name :)

If your question actually is "how to retrieve/print it?" to possibly modify it: gcc -dumpspecs

2. Can we change it?

You can supply an external one.

C.f. gcc --help
(-specs=<file>)

Does it create any problems?

Well, not if you know what you're doing.

There are _rare_ special cases when overriding the build-in specs makes sences, but in most occasions it doesn't.
