# Script to compile a resource file for a DLL in the same way that

# libtool would, if it knew about .rc files.

# This kinda sucks, but the alternative would be to teach autoconf,

# automake, and libtool about compiling .rc files.  That would be

# doable, but waiting for those changes to propagate to official

# versions of those tools would take some time.

# The command line arguments are:

# $1: the name of the .rc file to compile if it exists

# $2: the name of the resource libtool object file to produce

rcfile=$1

# uses .lo files which are the real object files in "this" directory,

# or it creates .o files in the .libs subdirectory, and the .lo file

# is a small text file. We try to deduce which case this is by

# checking if there are any .o files in .libs. This requires that the

# resource file gets built last in the Makefile.
