I built today libidn 1.23 using MinGW, and the test suite failed in
lib/gltests:

     make[4]: Entering directory `/d/usr/eli/utils/libidn-1.23/lib/gltests'
       CC     localename.o
     gcc.exe: ../../gl: linker input file unused because linking not done
     gcc.exe: ../../gl: linker input file unused because linking not done
     cc1.exe: ../../gl: No such file or directory
     cc1.exe: internal compiler error: Segmentation fault
     Please submit a full bug report,
     with preprocessed source if appropriate.
     See <URL:http://www.mingw.org/bugs.shtml> for instructions.
     make[4]: *** [localename.o] Error 1

Here's the full GCC command line:

     depbase=`echo localename.o | sed 's|[^/]*$|.deps/&|;s|\.o$||'`;\
          gcc -std=gnu99 -DHAVE_CONFIG_H -I. -I../..  
-DIN_LIBIDN_GNULIB_TESTS=1 -I. -I. -I../.. -I./../.. -I../../lib/gl 
-I./../../lib/gl ../../gl ../../gl -I/d/usr/include  -g -O2 -MT localename.o 
-MD -MP -MF $depbase.Tpo -c -o localename.o localename.c &&\
               mv -f $depbase.Tpo $depbase.Po

Note the two instances of "../../gl", which is certainly not TRT.  The
reason is this line in Makefile.am:

     AM_CPPFLAGS += $(top_builddir)/gl $(top_srcdir)/gl

which misses the "-I" part.

I guess no one ran these tests, at least not in the MinGW build...

After fixing this, all the tests pass (the tests that need symlinks
were skipped, as expected).

Thanks.
