On the pmax, the first I get when I try to compile is:

cc -O2  -Werror   -I. -I/usr/src/gnu/usr.bin/gdb -I/usr/src/gnu/usr.bin/gdb/../
.
./dist/gdb/config -I/usr/src/gnu/usr.bin/gdb/../../dist/gdb  
-I/usr/src/gnu/lib/
libbfd/obj.pmax -I/usr/src/gnu/usr.bin/gdb/../../dist/bfd 
-I/usr/src/gnu/usr.bin
/gdb/../../dist/include  -DHOST_NAME=\"mipsel--netbsd\"  
-DTARGET_NAME=\"mipsel-
-netbsd\" -DSVR4_SHARED_LIBS -c /usr/src/gnu/usr.bin/gdb/../../dist/gdb/jv-type
p
rint.c
