I am having trouble figuring out how the option processing is handled.
Possibly in gcc/gcc.c but I am stumped here.

Any pointers would be welcome.

Thanks.

The first thing is why don't you just create a alias in your shell forthis. If not

you also have to understand -lpthread is a linker to link in thelibrary. If you

really require to do then you will need to rewrite parts of the C++/Cfrontends.


Here is a link to what you will need to read:

Mostly it's adding the option so the first link should help it seems forunderstanding
