%_configure_gnuconfig_hack	1

# If defined, _configure_disable_silent_rules will cause --disable-silent-rules

# to be added to the list of options passed to the configure script.

# Eventually we'll want to turn this on by default, but this gives packagers a

# way to turn it back off.

# %_configure_disable_silent_rules 1

# This fixes various easy resolved configure tests that are compromised by LTO.

#

# We use this within the standard %configure macro, but also make it available

# for packages which don't use %configure

#

# The first three are common ways to test for the existence of a function, so

# we ensure the reference to the function is preserved

#

# The fourth are constants used to then try to generate NaNs and other key

# floating point numbers.  We then use those special FP numbers to try and

# raise a SIGFPE.  By declaring x & y volatile we prevent the optimizers

# from removing the computation

#

# The fifth (and worst) addresses problems with autoconf/libtool's approach

# to extracting symbols from .o files and generating C code.  In an LTO world

# types matter much more closely and you can't have an object in one context

# that is a function definition and a simple scalar variable in another.

# Thankfully HP-UX has always had that restriction and is supported by

# autoconf/libtool.  The insane sed script replaces the "generic" code with

# the HP-UX version.

#

# If we do not make changes, we put the original file back.  This avoids

# unnecessary rebuilds of things that may have dependencies on the configure

# files.
