build configuration (Debian i386, gcc 4.7.1-1, binutils 2.22-6.1)

Hi,

Trying to build glibc "master" (4d0ee855457e, "SH can do fanotify_mark,
too.", 2012-06-09), I tried the following:

 git clean -fdx
 git reset --hard
 mkdir BUILD
 cd BUILD
 ../configure --prefix=$HOME/opt/glibc --disable-static
 make

That works pretty well, until:

 gcc ../sysdeps/ieee754/flt-32/s_isnanf.c -c -std=gnu99 -fgnu89-inline  -O2
-Wall -Winline -Wwrite-strings -fmerge-a
 ../sysdeps/ieee754/flt-32/s_isnanf.c:37:1: error: `__EI___isnanf' aliased to
external symbol `__GI___isnanf'
 make[2]: *** [/home/jrn/src/glibc/BUILD/math/s_isnanf.os] Error 1
 make[2]: Leaving directory `/home/jrn/src/glibc/math'
 make[1]: *** [math/subdir_lib] Error 2
 make[1]: Leaving directory `/home/jrn/src/glibc'
 make: *** [all] Error 2

Known problem?  config.log attached.

This is a duplicate of bug 14281 - looks like a bug in Debian's gcc.

*** This bug has been marked as a duplicate of bug 14281 ***

Thanks.  Hmm, I need to get better at my bugzilla searching skills ---
quicksearch finds nothing, while query.cgi finds too much.  Next time
I'll just browse.
