# The order of the object files on the link command line affects the size of the resulting
# binary (at least on linux) which causes the size to differ between old and new build.

# Tell the compiler not to export any functions unless declared so in
# the source code. On Windows, this is the default and cannot be changed.
# On Mac, we have always exported all symbols, probably due to oversight
# and/or misunderstanding. To emulate this, don't hide any symbols
# by default.
# On AIX/xlc we need at least xlc 13.1 for the symbol hiding
# Also provide an override for non-conformant libraries.
