http://gcc.gnu.org/backends.html claims that "pdp11" is a supported
target, with these caveats:  narrow integer registers (duh), no IEEE
floats (duh), uses cc0 preprocessor, does not use define_peephole,
does not define prologue and/or epilogue RTL expanders, does not use
define_constants, and no ELF support.

SAXParserFactory [is] a hideous, evil monstrosity of a class that should
be hung, shot, beheaded, drawn and quartered, burned at the stake,
buried in unconsecrated ground, dug up, cremated, and the ashes tossed
in the Tiber while the complete cast of Wicked sings "Ding dong, the
witch is dead."  --Elliotte Rusty Harold on xml-dev
