You may need --disable-assembler if building universal binaries on
Darwin. This is because different files are built when assembler is
enabled, and there's no way to make it work with universal build.
If you want to keep the assembler code, consider building one
architecture at a time, and then combining the results to create
universal binaries (see lipo(1)).
MIPSpro 7.4.4m has been reported to produce broken code if using
the -O2 optimization flag ("make check" fails). Using -O1 should
work.

C99. You can safely override the test for C99 compiler by passing
ac_cv_prog_cc_c99= as the argument to the configure script.
There's no code to detect the amount of RAM on Tru64. It can be
added, but I currently don't know anyone who can test on Tru64.
For now, you may want to pass --enable-assume-ram=SIZE to the
configure script. See the section 2 in this file for details.
1.2.3. Windows
Building XZ Utils on Windows is supported under MinGW and Cygwin.
If the Autotools based build gives you trouble with MinGW, you may
want try the alternative method found from the "windows" directory.
Building XZ Utils on Windows is supported under MinGW + MSYS and
Cygwin. There is windows/build.sh to ease packaging XZ Utils with
MinGW + MSYS into a redistributable .zip or .7z file. See
windows/INSTALL-Windows.txt for more information.
MSVC doesn't support C99, thus it is not possible to use MSVC to
compile XZ Utils. However, it is possible to use liblzma.dll from
MSVC once liblzma.dll has been built with MinGW. The required
import library for MSVC can be created from liblzma.def using the
"lib" command shipped in MSVC:
It might be possible to build liblzma with a non-GNU toolchain too,
but that will probably require writing a separate makefile. Building
the command line tools with non-GNU toolchains will be harder than
building only liblzma.
lib /def:liblzma.def /out:liblzma.lib /machine:ix86
On x86-64, the /machine argument has to naturally be changed:
lib /def:liblzma.def /out:liblzma.lib /machine:x64
Even if liblzma is built with MinGW, the resulting DLL or static
library can be used by other compilers and linkers, including MSVC.
Thus, it shouldn't be a problem to use MinGW to build liblzma even
if you cannot use MinGW to build the rest of your project. See
windows/README-Windows.txt for details.
1.2.4. DOS
There is an experimental Makefile in the "dos" directory to build
XZ Utils on DOS using DJGPP. Support for long file names (LFN) is
needed.

GNU Autotools based build hasn't been tried on DOS. If you try, I
would like to hear if it worked.
1.2.5. OS/2
You will need to pass --disable-assembler to configure when building
on OS/2.
To omit large number of harmless warnings about visibility support,
pass gl_cv_cc_visibility=no as an argument to the configure script.
This isn't mandatory since it should have no effect on the resulting
