# Compiler options

help
gcc is the full-blown GNU compiler. This is what most people will choose.
gcc supports many languages, a powerful code parser, optimised binary
output, and lots of other features.

Enter the snapshot date in the form YYYYMMDD.
Snapshots are made every friday, at around 22:30 GMT+1,
so look at your calendar to find a suitable date.
Also, know that crosstool-NG does *not* carry any patch
for the gcc-4.4 snapshots. So, you may have to answer
'y' to CUSTOM_PATCH, and set CUSTOM_PATCH_DIR adequately.

Let configure decide if setjmp/longjmp should be used to handle
exceptions.
Choose that if you trust configure to detect the correct settings.
This is the default choice.
config CC_SJLJ_EXCEPTIONS_USE

help
Do not use setjmp/longjmp for exceptions.
This is gcc's --disable-sjlj-exceptions configure switch.
Choose that if you want to not use setjmp/longjmp to handle exceptions.

The core gcc is a stripped down, C-only compiler needed to build
the C library. Kinda bootstrap gcc, if you wish.
