Bugzilla Bug 172533

The test autoopts/test/immediate.test fails if CFLAGS contains any of the debug
flags (apart from -g).  This is because it tries to filter those flags out by
using this:

  CFLAGS="-g `echo ${CFLAGS} | \
    sed 's,-O2,,;s/-g//'`"

which clearly replaces -ggdb2 (for example) with -gdb2 - which isn't a valid
CFLAG and the test compilation fails.  A simple fix is to make the sed script a
little more consistent.  The following works:

  CFLAGS="-g `echo ${CFLAGS} | \
    sed 's,-O2,,;s/-g[^ \t]*//g'`"

I figured really they want to remove any -g* flags.  Patch to follow.

Fixup insufficient sed script to remove any -g* debug flag, not just drop '-g'

I meant it is replaced with 'gdb2' (no '-').

i've gone with:
+  sed 's,-O2,,;s/-g[^[:space:]]*//'`"

cheers

I just found two new gcc parameters that the fix in the ebuild doesn't handle
but the fix applied upstream does.

--param max-gcse-passes=4
--param max-gcse-memory=209715200

I suggest changing the patch in ebuild to use the sed script from upsteam with
sed 's,-O2,,;s/[ \t][ \t]*-g[^ \t]*[ \t][ \t]*/ /'
