+/*
+ Interface for perl to IO functions.
+ There is a hierarchy of Configure determined #define controls:
+ USE_STDIO - forces PerlIO_xxx() to be #define-d onto stdio functions.
+ This is used for x2p subdirectory and for conservative
+ builds - "just like perl5.00X used to be".
+ This dominates over the others.
+
+ USE_PERLIO - The primary Configure variable that enables PerlIO.
+ If USE_PERLIO is _NOT_ set
+ then USE_STDIO above will be set to be conservative.
+ If USE_PERLIO is set
+ then there are two modes determined by USE_SFIO:
+
+ USE_SFIO - If set causes PerlIO_xxx() to be #define-d onto sfio functions.
+ A backward compatability mode for some specialist applications.
+
+ If USE_SFIO is not set then PerlIO_xxx() are real functions
+ defined in perlio.c which implement extra functionality
+ required for utf8 support.
+
+ One further note - the table-of-functions scheme controlled
+ by PERL_IMPLICIT_SYS turns on USE_PERLIO so that iperlsys.h can
+ #define PerlIO_xxx() to go via the function table, without having
+ to #undef them from (say) stdio forms.
