The output does not mean that eCos global CFLGAGS for your *arm-elf*
target contain CYGBLD_GLOBAL_WARNFLAGS as a part of CFLAGS, mine
cdl_option CYGBLD_GLOBAL_CFLAGS {
...
# Default value: CYGBLD_GLOBAL_WARNFLAGS . CYGBLD_ARCH_CFLAGS .
...
the output does mean that CYGBLD_GLOBAL_WARNFLAGS option in your CDL
(and I know there is it in ecos.ecc :-) I think your CFLAGS has not such
a concatenation.

Bad news for old sources are processed by newest compilers. Could you
please show your ecos.mak? To comparison mine (NXP ARM7TDMI)
% grep CFLAGS /tmp/t/install/include/pkgconf/ecos.mak
ECOS_GLOBAL_CFLAGS = -Wall -Wpointer-arith -Wstrict-prototypes -Wundef
-Woverloaded-virtual -Wno-write-strings -mno-thumb-interwork -mcpu=arm7tdmi -g
-O2 -ffunction-sections -fdata-sections -fno-rtti -fno-exceptions
I think that -Wno-write-strings from CYGBLD_GLOBAL_WARNFLAGS (it is a
really part of CYGBLD_GLOBAL_CFLAGS for *arm-eabi* targets in eCos CVS)
does fulfill main "clean-up" job for any old sources and for BSD
sources as well.

I will look on the same targets.
