* configure: Detect platforms which don't reveal declarations

in C headers which are extensions to standard C, like popen or fileno,
in response to standard feature selection macros like -D_POSIX_SOURCE.
MinGW and Cygwin are offenders.  These platforms hide the declarations
when gcc is in -ansi mode, by testing for __STRICT_ANSI__. Turns out,
however, that -U__STRICT_ANSI__ on the gcc command line strips this
away, causing the declarations to be revealed.

* lib.c, parser.l, stream.c, utf8.c: Removed the declarations which
compensated for the above problem. Yippee!  Fuck you, stupid Cygwin
troglodytes, and the MinGW horse you rode in on.
