If I omit libc.a, I get this:
ld: warning: cannot find entry symbol fftEntry AT 12;
defaulting to 10001000
djbfft2d.o(.text+0x3c0):djbfft2d.cpp: undefined
reference to `_alloca'
djbfft2d.o(.text+0x44c):djbfft2d.cpp: undefined
reference to `malloc'
djbfft2d.o(.text+0x7a7):djbfft2d.cpp: undefined
reference to `free'

LIBS is empty. DLLNAME is djbfft.dll.

AS is as.

Any difference in doing so ? I got the above Makefile

Thanks
