[llvm-commits] CVS: llvm/autoconf/configure.ac

[Reid Spencer]

Changes in directory llvm/autoconf:

configure.ac updated: 1.186 -> 1.187
---
Log message:

In support of PR418: http://llvm.cs.uiuc.edu/PR418 :
Make sure that -lpthread gets added to LIBS variable which puts it at the
end of the tools' link commands, if libpthread.a is found. 

Add a test for pthread.h so we can use #ifdef HAVE_PTHREAD_H
