.rodata section defined as Writeable as well as Text program header

[Alex Kogan]

Hello, all.

Another  animality I see when compiling current (2005-12-27) glibc sources
by gcc 4.1 on RHEL4/PowerPC machine: in libm.so.6 library,  .rodata is
defined as Writeable, and so Text program header does.
Section headers:
  [12] .text             PROGBITS        0000a390 00a390 0361c0 00  AX  0

  [14] .fini             PROGBITS        00040550 040550 000038 00  AX  0

 Section to Segment mapping:

.gnu.version_r .rela.dyn .rela.plt .init .text .fini .rodata .interp
.eh_frame
   ...

The configuration I use:
../glibc-2005-12-27/configure --prefix=/opt/biarch/20050923
--build=powerpc-unknwon-linux-gnu
--with-headers=/opt/biarch/20050923/include
--with-binutils=/opt/biarch/20050923/bin --libdir=/opt/biarch/20050923/lib
--enable-add-ons=linuxthreads --enable-add-ons=nptl --with-selinux

Any ideas why it happens?

Thanks in advance,
