Tried to test current CVS version of GSL with DJGPP
(target=i586-pc-msdosdjgpp).

At first there were some problems to build it at all and to run tests:

1) Makefile.in and gsl/Makefile.in uses 'ln' directly, so one cannot replace it on 
systems where are no symbolic links. Editted files to workaround problem

2) Many tests opens binary files without specifying binary mode.
So tests breaks for MS-DOS and perhaps Windows related targets.
Editted files and put fopen ("test.dat" , "[rw]b") were needed.

Here is list of changes:

sh-2.03$ grep -n fopen\ \(\"test[.]dat `find . -name '*.c'`
./block/test_complex_source.c:76:    FILE *f = fopen ("test.dat", "wb");
./block/test_complex_source.c:94:    FILE *f = fopen ("test.dat", "rb");
./block/test_source.c:78:    FILE *f = fopen ("test.dat", "wb");
./block/test_source.c:95:    FILE *f = fopen ("test.dat", "rb");
./histogram/test.c:425:    FILE *f = fopen ("test.dat", "wb");
./histogram/test.c:431:    FILE *f = fopen ("test.dat", "rb");
./histogram/test2d.c:573:    FILE *f = fopen ("test.dat", "wb");
./histogram/test2d.c:579:    FILE *f = fopen ("test.dat", "rb");
./matrix/test_complex_source.c:149:    FILE *f = fopen ("test.dat", "wb");
./matrix/test_complex_source.c:169:    FILE *f = fopen ("test.dat", "rb");
./matrix/test_source.c:356:    FILE *f = fopen ("test.dat", "wb");
./matrix/test_source.c:372:    FILE *f = fopen ("test.dat", "rb");
./vector/test_complex_source.c:161:    FILE *f = fopen ("test.dat", "wb");
./vector/test_complex_source.c:177:    FILE *f = fopen ("test.dat", "rb");
./vector/test_source.c:294:    FILE *f = fopen ("test.dat", "wb");
./vector/test_source.c:307:    FILE *f = fopen ("test.dat", "rb");
sh-2.03$

3) There are huge number filename conflicts for DOS. As I run tests
in DOS box under Win98 SE without setting NameNumericTails=0
then I didn't get related failures

4) Only testsuite problems I met after that was in directory 
specfunc:
	test.exe crashes in different places and different ways (SIGSEGV,
	SIGILL, ...) so I suspect some memory corruption (or use of uninitialized
	data). Unfortunatelly (according "Murphys law") it doesn't crash at all
	when I'm trying to run it under gdb (in this case all tests suceeds)
