Yes, but not with the SGI X development environment.  We built MIT X.
MIT X.V11R4 comes with an sgi config file and a much fixed set of Xw
widgets in contrib/toolkits/Xw.  (WARNING: Do not try to use the Xw
widgets in the MIT R3 source with the MIT R3 includes or libXt.  It
doesn't work, for reasons documented in the R3
doc/tutorials/r3widgets.ms document)

/usr/include? /usr/lib/uopt is the MIPS optimizer, which dumps core on
a few files in Xw when compiling with -O.  (if it's any consolation,
it did this on the DECstation 3100 as well) Compile with
	make -k
then go back to Xw and use
	make CDEBUGFLAGS=-g

to recompile the files that caused cc to dump core.  Alternatively,
you can opt for the lower performance, high correctness side of the
world and compile everything without -O, which is what we did.  (When
compiling something the size of X, even looking through the output of
the make to find errors is exhausting.  And then there's programs that
work when compiled without -O but die when compiled with -O, like
contrib/clients/pbmplus/ppm/giftoppm.c)

Perhaps someone from SGI/MIPS would care to compile all of X.V11R4
before Irix3.3 is released -- X makes a great compiler test suite.

Yes.
