eCos compiled with gcc-3.4

[向 超]

I want to compile the eCos for MCF5272EVB which is supported by eCos. But I 
got the
follow error message:


/opt/ecos/build/mcf5272_install/include/pkgconf/mlt_m68k_mcf52xx_mcf5272_mcf5272 
3_ram.ldi:53:1: pasting "." and "romvec" does not give a valid 
preprocessing token

The file mlt_m68k_mcf52xx_mcf5272_mcf5272 3_ram.ldi is :

    CYG_LABEL_DEFN(__heap1) = ABSOLUTE (__heap1_start);

    SECTIONS_END
}

I have marked the line 53. This file is included in the link command file, 
but I can't find
GENERIC_SECTION command in the syntax reference of ld script language. What 
does it mean?

Sorry, I am a newbie for eCos. Could anybody help me?
thx.

The version in anoncvs is not supported.
http://ecos.sourceware.org/hardware.html clearly lists the target as
non-functional, as does
http://ecos.sourceware.org/ecos/boards/mcf5272c3.html
