How to save intermediate files (pre-processing files: *.i ) while compiling gcc from source

[David Yang <abiao.yang@xxxxxxxxx>]

Hi,

Is there possible to save intermediate files while compiling gcc from source?

for compiling the gcc 3.4.0 source code. I can get some pre-processing
files (the *.i files) while using the follwoing command:

./configure && make CC="gcc --save-temps" -i

but this does not work for gcc 4.x.x version. Do i need to edit the makefile?

Thank you very much and looking forward to hearing from you.

Best regards,

-David
