C inline information is saved in +default-machine+, which was
previously a constant. However, the value assigned to
+default-machine+ is recomputed during load and compile
time. Technically, assigning a constant a new value which is not eql
to the old one is undefined behaviour in the ANSI standard. What ECL
did was simply to reassign the constant when compiling
cmpc-machine.lsp. However, this meant that the inline information
which was added to +default-machine+ when loading sysfun.lsp was
lost. Thus, all ECL source files compiled after cmpc-machine.lsp were
compiled without inline information. We prevent this by using an
ordinary variable *default-machine* instead of a constant.
