commit 2133b11083c9b7c671c2ee175461d9a206c87a29
Author: Ralf Wildenhues <[EMAIL PROTECTED]>
Date:   Thu Jun 19 19:35:52 2008 +0200

    Newer Intel compilers do not grok -KPIC any more.
    
    * libltdl/m4/libtool.m4 (_LT_COMPILER_PIC) [linux] <icc, icpc>:
    Use -fPIC, newer Intel compilers (icc 10, ifort 9) reject -KPIC.
    * tests/localization.at: Skip test if the compiler fails merely
    due to the locale setting.
    * THANKS: Update.
    Report by Vincent Lefevre.
