[MACTCL] A hanging Wish shell...

[Alfred V. H. <va...@ma...>]

Got a problem with the Wish Shell application. It hangs forever, its startup
time is relatively long as measured by a long period of bouncing of the app
icon in the Dock. In order to get Wish build I had to comment out #include
<pthread.h> in tkMacOSXAppInit.c and in tkMacOSXXStubs.c. Those lines causes
compiler errors of previous declaration of e.g. execv in unistd.h:45 and
conflicting types of execv in unistd.h:142.

Could the commenting out of the pthread header file be the reason of this
hanging?
