I'm having trouble getting pthreads working with GNAT 2.04 under Linux.
I have the binary version from ftp.cs.nyu.edu, and am using 
pthreads 1.60beta2.  I get all kinds of undefined symbols when linking,
like the following:

$ gnatbl tetris.ali -L/usr/tmp/pthreads/config -lpthread

/home/mcculley/gcc-2.6.3/ada/rts/i-cpotim.adb(.text+0x33): undefined reference to `clock_gettime'
/usr/lib/gcc-lib/i486-linux/2.6.2/adalib/i-cporte.o: In function `interfaces__c__posix_rte__setjmp':
/home/mcculley/gcc-2.6.3/ada/rts/i-cporte.adb:255: undefined reference to `setjmp'
/usr/lib/gcc-lib/i486-linux/2.6.2/adalib/i-cporte.o: In function `interfaces__c__posix_rte__sigsetjmp':
/home/mcculley/gcc-2.6.3/ada/rts/i-cporte.adb:267: undefined reference to `sigsetjmp'


I'm also curious about the /home/mcculley/ paths.  They seem a bit strange.

Any tips?  Thanks.
