[openssl-dev] OpenSSL-1.1 make depend

[Erik Forsberg]

In case its not clear, the difference in the input to clean-depend.pl
is that when using Solaris cc, /usr/openwin/bin/makedepend is used
instead of gcc -M

Still, considering that, the problem is elsewhere, as I tried
various styles of input and could not see  any correlation
