>Description:
While trying to build the "ImageMagick" package "egcs" died with an
internal compiler error:

*** Error code 1

With optimization level reduced to "-O" the source can be compiled.
However, because "-O2" is the default for "arm32" in "sys.mk" this bug
should really be fixed.

>How-To-Repeat:
cd /usr/pkgsrc/graphics/ImageMagick
make

>Fix:
Sorry, I don't now.
