Re: configure + make fails on AIX due to missing -lpthread

   After the following:
    ./configure --prefix=/opt --sysconfdir=/var/rcs/etc
   --sharedstatedir=/var/rcs/com --localstatedir=/var/rcs
   --mandir=/usr/share/man --infodir=/opt/share/info/rcs

   make proceeds normally until the programs need to 'link' -
   ident is the first failure:

Thanks for reporting this.  First questions: Was this method
used for previous versions of GNU RCS?  If not, how were
previous versions built?

   To succeed, copy/paste then add -lpthread and the command
   succeeds

I wonder where those .pthread_* symbols are being referenced.
RCS is definitely single-threaded.  Maybe something from gnulib?

   Just let me know what else you would like to receive.

Could you please re-run w/o "-lpthread", using those options
indicated in the error message "to obtain more information"?
Also, maybe nm(1) can tell where those symbols are referenced.
E.g., i'd be interested in seeing the output of:

 nm lib/*.o src/*.o src/libparts.a

(I presume AIX nm(1) works similarly to GNU/Linux nm(1); feel
free to substitute a more appropriate command as you see fit.)

Lastly, could you please also attach config.status and
lib/config.h (all from the original build, w/o "-lpthread")?
