Issue with AC_LANG_PROGRAM

[Miguel Guedes]

Hello,


I am using AC_LANG_PROGRAM to test for libboost_system and it invokes 
gcc/g++ in the following way:

configure:3975: g++ -o conftest -g -O2  -lboost_system conftest.cpp

The above results in a few errors and doesn't link even though the 
library in question is present in the system.  This is because the 
source file should be at the front in the call to g++, e.g.:

  g++ conftest.cpp -o conftest -g -O2  -lboost_system

What can be done with autoconf to overcome this limitation?  Can the 
parameter order be customized somehow or perhaps some other macro be used?
