rename HAVE_CONFIG_H to HAVE_ASN1C_CONFIG_H

[mtfurlan]

other projects like CppUTest also use HAVE_CONFIG_H so this will reduce
conflicts

Closes #201

Hm, I didn't expect this to fail to build, but clearly I did it wrong

[mtfurlan]

Okay so HAVE_CONFIG_H is generated by autotools with configure.ac:AC_CONFIG_HEADER([config.h])

So to do this we would have to rename config.h to config_asn1c.h
Is this still acceptable?

[mtfurlan]

Okay I think HAVE_CONFIG_H is hardcoded by autoreconf and cannot be changed?

Now, wait a bit. Why are we interfering with the asn1c compiler build? It's not supposed to get linked with any other package out library, so whatever config.h other oxidates might have, should play no role here.

What are you trying to accomplish?

I agree. It seems like more code is being added in order to fix something that is a "slight annoyance".
cpputest is not even used in asn1c.

What are you trying to accomplish?

[mtfurlan]

I'm generating asn1c, adding the files to a cmake target, and then linking that target against my code, my tests, and cpputest, and somehow HAVE_CONFIG_H is getting set by them

It seemed silly that two projects were using the same name for something, but now that I've read autoconf I'm pretty sure the name is set by them, so we cannot change it
