Hello,
This change adjusts the processing of --sysroot to save the option in the
internal "switches" array, which lets self-specs test for it and provide a
default value possibly dependent on environment variables, as in
--with-specs=%{!-sysroot*:--sysroot=%:getenv("WIND_BASE" /target)}
This helps the use we have of self specs for VxWorks, and
was bootstrapped and regression tested on native 64bit linux.
Ok to commit ?
Thanks in advance,
With Kind Regards,
