# A few convenience macros for Mesa, mostly to keep all the platform
# specifics out of configure.ac.
# MESA_PIC_FLAGS()
#
# Find out whether to build PIC code using the option --enable-pic and
# the configure enable_static/enable_shared settings. If PIC is needed,
# figure out the necessary flags for the platform and compiler.
#
# The platform checks have been shamelessly taken from libtool and
# stripped down to just what's needed for Mesa. See _LT_COMPILER_PIC in
# /usr/share/aclocal/libtool.m4 or
# http://git.savannah.gnu.org/gitweb/?p=libtool.git;a=blob;f=libltdl/m4/libtool.m4;hb=HEAD
