[Buildroot] [PATCH 1/2] gcc: remove option on SJLJ exceptions
Thomas Petazzoni

Wed Jul 28 10:10:12 UTC 2010
This is a very advanced option, and it seems, according to
http://choices.cs.uiuc.edu/exceptions.pdf that SJLJ exceptions aren't
really interesting.
Users really interested by this can always use the
BR2_EXTRA_GCC_CONFIG_OPTIONS is they want.
