--- Comment #2 from Mark Wielaard <mark at klomp dot org> ---
Note that there should be a configure test to check that your compiler has =
all
capabilities to build elfutils:

# We use -std=3Dgnu99 but have explicit checks for some language constructs
# and GNU extensions since some compilers claim GNU99 support, but don't
# really support all language extensions. In particular we need
# Mixed Declarations and Code
# https://gcc.gnu.org/onlinedocs/gcc/Mixed-Declarations.html
# Nested Functions
# https://gcc.gnu.org/onlinedocs/gcc/Nested-Functions.html
# Arrays of Variable Length
# https://gcc.gnu.org/onlinedocs/gcc/Variable-Length.html

Normally if your compiler doesn't support those language constructs the
"Checking for for gcc with GNU99 support..." test should fail. If it doesn'=
t in
your case we might have to tighten up the configure check.
