Hi, I try to revert the patch to enable the COFF ouput format to the LynxOS target. Now the compilation fails with this error: gcc -g -DENABLE_CHECKING -DENABLE_ASSERT_CHECKING -DIN_GCC -W -Wall -Wwrite- strings -Wstrict-prototypes -Wmissing-prototypes -DHAVE_CONFIG_H -o cc1 \ c-parse.o c-lang.o stub-objc.o attribs.o c-errors.o c-lex.o c-pragma.o c -decl.o c-typeck.o c-convert.o c-aux-info.o c-common.o c-opts.o c-format.o c-sem antics.o c-incpath.o cppdefault.o c-ppoutput.o c-cppbuiltin.o prefix.o c-objc-co mmon.o c-dump.o c-pch.o c-gimplify.o tree-mudflap.o c-pretty-print.o main.o li bbackend.a ../libcpp/libcpp.a ../libcpp/libcpp.a ../libiberty/libiberty.a libbackend.a(i386.o)(.text+0x7e12): In function `ix86_file_end': /home1/h2/data/result/trace/src/gcc/build/gcc/../../gcc-4.0.1/gcc/config/i386/i3 86.c:3927: undefined reference to `ASM_DECLARE_FUNCTION_NAME' collect2: ld returned 1 exit status I found that macro in several configuration headers for others platforms, but no for LynxOS. Anyone knows how should I define that macro for LynxOS? or is it specific to ELF targets?
