# FreeBSD ELF startup code for Free Pascal for dynamical linking to libc.
#
# To avoid needing a "COMPAT" system, patch the constant following the
# "FreeBSD" field in the abitag to the relevant ABI number
# Some versions of the "file" command support
# visualizing this constant. If not use elfdump, or patch
# automatically using the ../i386/identpatch.sh script
#
# some typical values:
#
# freebsd 5.4 504000
# freebsd 6.3 (prerelease) : 603100
# freebsd 7.0 700055
# freebsd 8.0 800500 (-stable)
# FreeBSD 9.0 900044
