I'm working with asn1c and CppUTest, and both projects use HAVE_CONFIG_H to mean things, and CppUTest defining it as a public compile definition is causing issues for the asn1c code

I would really like if we could rename the one in this repo to CPPUTEST_HAVE_CONFIG_H
From the comments in the file, it looks like it isn't supposed to be user facing, but searching github issues shows that I personally have had to define it manually in the past

So can we deprecate HAVE_CONFIG_H in favour of CPPUTEST_HAVE_CONFIG_H but support both?

#if defined(HAVE_CONFIG_H) || defined(CPPUTEST_HAVE_CONFIG_H)
