Hi, after reading [1] and [2] I'm a bit confused. I'd like to know how I should go about building GCC such that I can choose between SJLJ and ZCX at compile time, using --rts=sjlj. From [2] it looks like this is a configure-time option only. Is it necessary to configure gcc twice and produce two different libgnats? Is it necessary to install two compilers?
