I'm trying to build a DLL from the AFsp-Routines (to those who
unfamiliar wtih this routines: the library contains powerful routines
for Audio File Signal Processing (AFsp))

As a starting point I have used the description given by John Cerney
<j-cerney1 AT ti DOT com> in his mail from Wed, 5 Mar 1997 with the subject
"Building a relocatable DLL - example".

The given script works quite well apart from the fact that each time the
linker (ld) is called the following error message appears:

C:/Global/B20/H-i586-cygwin32/i586-cygwin32/lib/libcygwin.a(libccrt0.o):

In function `cygwin_crt0_common(int (*)(int, char **, char **))':
/home/noer/src/b20/comp-tools/devo/winsup/libccrt0.cc:65: undefined
reference to
 `GetModuleHandleA AT 4'

If possible, please tell me if this is a major problem (unsupported
function/bug) or just a stupid fault.

Thanks very much Lampos.
