Problems upgrading a BSP from RTEMS 4.5 to 4.6.2

Hello all,
Thanks in advance for any help and suggestions.
I'm working on a research project using the RTEMS 4.6.2 on a RAMiX PMC694
card. The BSP is working fine under the 4.5, but the RTEMS is not
compiling under the 4.6.2.
This is what I have done so far (Please let me know if there is a better
way do do it):
1) Copied the old pmc694.cfg into make/custom, and modifed it to reflect
the new changes in 4.6.2 (based on some posts on this list).
2) Added the pmc694.cfg into make/custom/Makefile.am
3) Copied the pmc694 folder into c/src/lib/libbsp/powerpc/pmc694
3) Modifed the bsp_specs in pmc694/ to reflect the changes.
4) Created new Makefile.am and configure.ac files in pmc694/ and
Makefile.am files in the subfolders (the old version only had Makefile.in
files).
5) I have made a lot of changes/fixes to the Makefiles, and at the end I'm
stuck with the following error:

# This section makes the target dependent options file.
# NDEBUG (C library)
# if defined asserts do not generate code. This is commonly used
# as a command line option.
#
# RTEMS_TEST_NO_PAUSE (RTEMS tests)
# do not pause between screens of output in the rtems tests
#
# STACK_CHECKER_ON (RTEMS support code)
# If defined, stack bounds checking is enabled.
#
# STACK_CHECKER_REPORT_USAGE (RTEMS support code)
# If this and STACK_CHECKER_ON are defined, then a report on stack usage
# per task is printed when the program exits.
#
# RTEMS_DEBUG (RTEMS)
# If defined, debug checks in RTEMS and support library code are enabled.
#
# CONSOLE_USE_INTERRUPTS (pmc694_bsp)
# The pmc694 console driver has the structure to operate in either
# polled or interrupt mode. However both modes only trap to the
# monitor currently.
#
# PPC_USE_DATA_CACHE (RTEMS PowerPC port)
# If defined, then the PowerPC specific code in RTEMS will use
# data cache instructions to optimize the context switch code.
# This code can conflict with debuggers or emulators.
#
# PPC_VECTOR_FILE_BASE (ppc)
# This defines the base address of the exception table.
# NOTE: Vectors are actually at 0xFFF00000 but file starts at offset
0x0100
#
# PPC_ABI (ppc)
# This defines the calling convention (Application Binary Interface)
# used in this configuration. EABI is the only one supported.
#
# PPC_ASM (ppc)
# This defines the assembly language format used in this configuration.
# ELF is the only one supported.
#
# PPC_USE_SPRG (RTEMS PowerPC port)
# If defined, then the PowerPC specific code in RTEMS will use some
# of the special purpose registers to slightly optimize interrupt
# response time. The use of these registers can conflict with
# other tools like debuggers.
