-# This script munges the config.h to mark EBP unavailable so that the ffmpeg
-# library can be compiled as WITHOUT -fomit-frame-pointer allowing for
-# breakpad to work.
-#
-# Without this, building without -fomit-frame-pointer on ia32 will result in
-# the the inclusion of a number of inline assembly blocks that use too many
-# registers for its input/output operands.  This will cause gcc to barf with:
-#
-#   error: can't find a register in class ‘GENERAL_REGS’ while reloading ‘asm’
-#
-# This modification should only be required on ia32, and not x64.
-#
-# Note that HAVE_EBX_AVAILABLE is another flag available in config.h.  One would
-# think that setting this to 0 would allow for ffmpeg to be built with -fPIC.
-# However, not all the assembly blocks requiring 6 registers are excluded by
-# this flag.
