building gnat-4.9 on kfreebsd/Debian

[Xavier Grave <xavier.grave@ipno.in2p3.fr>]

Hi everybody,

I get this strange error during a build of gnat-4.9

build/genhooks -d \
                        ../../src/gcc/doc/tm.texi.in > tmp-tm.texi
genhooks: No place specified to document hook TARGET_ASM_OPEN_PAREN

make[5]: *** [s-tm-texi] Error 1
make[5]: *** Waiting for unfinished jobs....
rm gfdl.pod cpp.pod fsf-funding.pod gcov.pod gcc.pod
make[5]: Leaving directory 
`/home/xavier/gnat-lab/org.debian.gnat-4.9/build/gcc'
make[4]: *** [all-stage1-gcc] Error 2

my google search isn't very successful for the moment, if anybody have 
any idea...
