the recent re-ignition of the discussion about supporting other
compilers, at least for userland (which I too would really appreciate!):

        gcc -g -O2 -pipe -pedantic -W -Wall -Wshadow -Wswitch -Wreturn-type -Wpointer-arith -Wconversion -Wimplicit -Wmissing-declarations -Wmissing-prototypes -Wstrict-prototypes -Wcast-qual -Wno-format-extra-args -c spool.c
