 the @samp{--nfp} option is @emph{not} passed to @file{configure}, the
 directory @file{@var{machine}/fpu} is also used.  The operating system
 often has a @dfn{base operating system}; for example, if the operating

+system is @samp{Linux}, the base operating system is @samp{unix/sysv}.
 The algorithm used to pick the list of directories is simple:
 @file{configure} makes a list of the base operating system,
 manufacturer, CPU type, and operating system, in that order.  It then
 concatenates all these together with slashes in between, to produce a
-directory name; for example, the configuration @w{@samp{sparc-sun-sunos4.1}}
-results in @file{unix/bsd/sun/sparc/sunos4.1}.  @file{configure} then

+results in @file{unix/sysv/linux/i386/i686}.  @file{configure} then
 tries removing each element of the list in turn, so
-@file{unix/bsd/sparc} and @file{sun/sparc} are also tried, among others.
+@file{unix/sysv/linux} and @file{unix/sysv} are also tried, among others.
 Since the precise version number of the operating system is often not
 important, and it would be very inconvenient, for example, to have
-identical @file{sunos4.1.1} and @file{sunos4.1.2} directories,
+identical @file{irix6.2} and @file{irix6.3} directories,
 @file{configure} tries successively less specific operating system names
 by removing trailing suffixes starting with a period.
 
 As an example, here is the complete list of directories that would be
-tried for the configuration @w{@samp{sparc-sun-sunos4.1}} (without the
-@w{@samp{--nfp}} option):
