Hi.  I'm coming back to this, but I'm still unable to reproduce it.  Can
you (or someone) help me to reproduce the bug in simple steps, without a
Windows-platform?  I tried MinGW64 and it works:

jas@kaka:~/src$ tar xfa release/libidn-1.41.tar.gz 
jas@kaka:~/src$ cd libidn-1.41/
jas@kaka:~/src/libidn-1.41$ ./configure --host=x86_64-w64-mingw32
jas@kaka:~/src/libidn-1.41$ make
jas@kaka:~/src/libidn-1.41$ cat>foo.c
#include <stringprep.h>
#include <stdio.h>

void main (void)
{
  char *p;
  int rc;

  rc = stringprep_profile("foo", &p,
                          "SASLprep", STRINGPREP_NO_UNASSIGNED);
  printf ("rc %d str %s\n", rc, p);
}
jas@kaka:~/src/libidn-1.41$ x86_64-w64-mingw32-gcc -o foo.exe foo.c -Ilib/ 
lib/.libs/libidn.a 
jas@kaka:~/src/libidn-1.41$ wine64 ./foo.exe 
rc 0 str foo
jas@kaka:~/src/libidn-1.41$ file foo.exe 
foo.exe: PE32+ executable (console) x86-64, for MS Windows
jas@kaka:~/src/libidn-1.41$
