Hi,
Thanks for the bug report.

In VC6 the macro _DLL is defined when compiling the application using
a multi-threaded DLL (i.e. using /MD).  This picks up the correct
(dllimport) line.

It looks like VC7 doesn't define _DLL, but defines _WINDLL or _USRDLL
instead.

I will modify GSL to check #ifdef GSL_DLL instead of or in addition to
#ifdef _DLL.  In the meantime the simplest workaround may be to define
_DLL manually.

If you still have problems with #include <gsl/...> vs <...> could you
send a bug report for that.

best regards,
