Dear sir:

Now I am using GCC to compile a series .c file with a huge directory to search for header files.

I find on GCC command options, there seems to be the size limit on provided options.
>From my test on GCC version 4.8.5, the options length which I can provide seems to be limited at 12000 characters.

Can you share the size limit of GCC command options?

Best Regards
