[fpc-pascal] When is make cycle needed?

[Francisco Reyes]

Reading the docs I see there is a "make cycle" target, but I am not sure 
when it is necessary.

For the snapshot build seems that only "make all".
So when is make cycle needed?

Perhaps it is my newbiness, but the explanation in the manual doesn't mean 
much to me.

"make cycle" is a bootstrap of the compiler, and builds the rtl and compiler 
at least three times. The only starting point prerequisites are installed 
binutils and a starting compiler.
