I am installing an old(ish) distribution of TeX for 4.2 BSD. 
In the makefile there is a comment on the options for pc:
`We would like to use the -O flag here but it seems to produce incorrect code'. 
The distribution was intended for pc v3.1, does anybody know if this bug 
still exists ? TeX is a large program to run without the optimiser.

Little known (?) fact gathered from the same distribution the undocumented
(grr) flag -O on pxp (the Pascal prettyprinter) will convert cases with an
`others:' label into something pc can handle -- does anybody know why pc
itself wasn't modified ?
