There are some other related issues.  It looks like you changed the  
regexps which chose which files to build.  Those regexps were there  
so that the library glue files wouldn't be compiled and cause  
problems like this.  Some examples of these kinds of files are:

externals/cxc/cx.c
externals/iemlib/iemlib1/src/iemlib1.c
externals/iemlib/iemlib3/src/iemlib2.c
externals/iemlib/iem_t3_lib/src/iem_t3_lib.c

Here's the current error:
