 [sorry for the direct replay, but I cannot find any "Edit PR" button on 
 the page below & on the entire gants/gcc web. Thanks to point me to a 
 link, so that I can copy/paste the below in the gnats database].
 "-pthread" is documented as an RS6000/PowerPC option only:
         Adds support for multithreading with the pthreads library. This
         option sets flags for both the preprocessor and linker.
 However, this option exists for every architectures I worked with 
 (HP-UX, Linux, ia32, ia64...). It is even reported as part of the gcc specs:
 RedHat 8.0 / i386:
 gcc -v
 Reading specs from /usr/lib/gcc-lib/i386-redhat-linux/3.2/specs
 Configured with: ../configure --prefix=/usr --mandir=/usr/share/man --infodir=/usr/share/info --enable-shared --enable-threads=posix --disable-checking --host=i386-redhat-linux --with-system-zlib --enable-__cxa_atexit
 Thread model: *posix*
 gcc version 3.2 20020903 (Red Hat Linux 8.0 3.2-7)
 Debian Sarge / ia64:
  gcc-3.2 -v
 Reading specs from /usr/lib/gcc-lib/ia64-linux/3.2.3/specs
 Configured with: ../src/configure -v --enable-languages=c,c++,java,f77,proto,objc,ada --prefix=/usr --mandir=/usr/share/man --infodir=/usr/share/info --with-gxx-include-dir=/usr/include/c++/3.2 --enable-shared --with-system-zlib --enable-nls --without-included-gettext --enable-__cxa_atexit --enable-clocale=gnu --enable-java-gc=boehm --enable-objc-gc ia64-linux
 Thread model: *posix*
 gcc version 3.2.3 20030309 (Debian prerelease)
 So I have always assumed (as it always worked) that the description for 
 RS6000/PowerPC was Ok for every supported architecture.
 What I can observe in the current GCC I am using is that the linker 
 option (-lpthread) is set, but not the pre-compiler option
