having a lot of mingw build problems with atexit - what does it mean?

[Ed Hartnett]

Howdy all!

I am having a lot of trouble building my library with libtool under
mingw. I keep getting these errors relating to atexit. Can anyone
enlighten me as to what that is?

For example:

make check
/bin/sh ../libtool --tag=CC --mode=link gcc  -g -O2   -o libnetcdf.la
-rpath /usr/local/lib -Wl,--output-def,.libs/libnetcdf.def
-version-info 0:0:0 -no-undefined attr.lo ncx.lo putget.lo dim.lo
error.lo libvers.lo nc.lo string.lo v1hpg.lo var.lo  posixio.lo
libnetcdf2.la
