[llvm-commits] CVS: llvm/autoconf/README.TXT ltmain.sh

[Reid Spencer]

Changes in directory llvm/autoconf:

README.TXT updated: 1.2 -> 1.3
ltmain.sh updated: 1.3 -> 1.4
---
Log message:

Fix a bug in libtool's ltmain.sh. On Cygwin the "$output.exp" expression
expands to a full path name. Substitute $outputname.exp" instead and it
makes a viable temporary file name. This gets around the problem with lli
on Cygwin linking but not having any "C" library functions linked into it.

     This should correctly update the macro definitions in the libtool m4 
     files to match the version of autoconf that LLVM uses. This converts
     AC_HELP_STRING to AS_HELP_STRING and AC_TRY_LINK to AC_LINK_IFELSE, amongst
     other things. You may need to manually adjust the files.
