Re: Testing GSL with DJGPP

[Brian Gough <bjg at network-theory dot co dot uk>]

Thanks for the bug report. 

I'll add the "b" option to fopen() for binary files and substitute
$(LN_S) for ln -s in gsl/Makefile.am.  8+3 filenames don't seem
feasible with our naming scheme, so we'll have to let that slide. If
you discover any more facts about the crashes of specfunc/test.exe let
us know.

regards
Brian Gough
