Remove checks for ObjC runtime and foundation
After removal of cflib and tclobjc, there is no code requiring a Objective-C runtime or oundation libraries in base anymore. The autoconf macros PTHREAD_LIBS or PTHREAD_CFLAGS are not used and have no other references in the configure script. Therefore this is now also unused code and can safely be removed.

|

dnl
|
||||
dnl This macro figures out how to build C programs using POSIX threads.
|
||||
dnl It sets the PTHREAD_LIBS output variable to the threads library and
|
||||
dnl linker flags, and the PTHREAD_CFLAGS output variable to any special
|
||||
dnl C compiler flags that are needed. (The user can also force certain
|
||||
dnl compiler flags/libs to be tested by setting these environment
|
||||
dnl variables.)
|
||||
dnl
|
||||
dnl NOTE: You are assumed to not only compile your program with these
|
||||
dnl flags, but also link it with them as well. e.g. you should link
|
||||
dnl with $CC $CFLAGS $PTHREAD_CFLAGS $LDFLAGS ... $PTHREAD_LIBS
|
||||
dnl $LIBS
|
||||
dnl
|
||||
dnl If you are only building threads programs, you may wish to use
|
||||
dnl these variables in your default LIBS, and CFLAGS:
|
||||
dnl
|
||||
dnl LIBS="$PTHREAD_LIBS $LIBS"
|
||||
dnl CFLAGS="$CFLAGS $PTHREAD_CFLAGS"
|
||||
dnl
|
||||
dnl In addition, if the PTHREAD_CREATE_JOINABLE thread-attribute
|
||||
dnl constant has a nonstandard name, defines PTHREAD_CREATE_JOINABLE to
|
||||
dnl that name (e.g. PTHREAD_CREATE_UNDETACHED on AIX).
|
||||
dnl
|
||||
dnl ACTION-IF-FOUND is a list of shell commands to run if a threads
|
||||
dnl library is found, and ACTION-IF-NOT-FOUND is a list of commands to
|
||||
dnl run it if it is not found. If ACTION-IF-FOUND is not specified, the
|
||||
dnl default action will define HAVE_PTHREAD.
|
||||
dnl
|
||||
dnl Please let the authors know if this macro fails on any platform, or
|
||||
dnl if you have any other suggestions or comments. This macro was based
|
||||
dnl on work by SGJ on autoconf scripts for FFTW (www.fftw.org) (with
|
||||
dnl help from M. Frigo), as well as ac_pthread and hb_pthread macros
|
||||
dnl posted by Alejandro Forero Cuervo to the autoconf macro repository.
