--disable-shared don't provide a shared libgcc
--enable-languages=LIST specify which front-ends to build
--disable-rpath do not hardcode runtime library paths
- --enable-initfini-array use .init_array/.fini_array sections
--enable-sjlj-exceptions
arrange to use setjmp/longjmp exception handling
--enable-secureplt enable -msecure-plt by default for PowerPC
--enable-gnu-indirect-function
enable the use of the @gnu_indirect_function to
glibc systems
+ --enable-initfini-array use .init_array/.fini_array sections
--enable-comdat enable COMDAT group support
--enable-gnu-unique-object
enable the use of the @gnu_unique_object ELF
--with-as arrange to use the specified as (full pathname)
--with-stabs arrange to use stabs instead of host debug format
--with-dwarf2 force the default debug format to be DWARF 2
+ --with-native-system-header-dir=dir
+ use dir as the directory to look for standard
+ system header files in. Defaults to /usr/include.
--with-build-sysroot=sysroot
use sysroot as the system root during the build
--with-sysroot[=DIR] search for usr/lib, usr/include, et al, within DIR
--with-gc={page,zone} choose the garbage collection mechanism to use with
the compiler
--with-system-zlib use installed libz
- --with-slibdir=DIR shared libraries in DIR [LIBDIR]
--with-linker-hash-style={sysv,gnu,both}
specify the linker hash style
