 From Makefile (line 104):

ifndef FPC
ifdef PP

See Makefile from line 109 onwards.  It first looks for fpc(.exe) on the 
path.  If it finds that, it gets the real compiler exe with -PB.  If 
fpc(.exe) isn't found, it tries to find ppc386(.exe) on the path.

On Windows, I usually install latest fpc release, then I check out 
lazarus and build it.  That's pretty simple, no?
