In the created libtool script a check is done on the file
'src/.libs/libassuan.def' to see if this is correct to create a
libassuan-0.dll.def file from.

The script checks if the first line of 'libassuan.def' contains 'EXPORTS' and if
not, first echo's this itself to a new file 'libassuan-0.dll.def', before
cat-ting 'libassuan.def' to the end of the new file. The problem is, however,
that 'libassuan.def' DOES contain the EXPORTS line, but not on line 1, as there
is a comment section there describing what the file is (and some licensing stuff).

The check looks something like this (from 'libtool' created by ./configure on

Win7 with mingw):

archive_expsym_cmds="if test \\\"x\\\\$SED 1q \$export_symbols\\\\\\" =
xEXPORTS; then

  cp \$export_symbols \$output_objdir/\$soname.def;
else
  echo EXPORTS > \$output_objdir/\$soname.def;
  cat \$export_symbols >> \$output_objdir/\$soname.def;
fi~
\$CC -shared \$output_objdir/\$soname.def \$libobjs \$deplibs

\$compiler_flags -o \$output_objdir/\$soname \${wl}--enable-auto-image-base

-Xlinker --out-implib -Xlinker \$lib"

The test on the first line is broken. It should probably be something like

(ignoring the escaping needed):

if grep EXPORTS $export_symbols; then
