Subject: Adapt conservative default to the compiler support
X-Git-Url: https://git.llucax.com/software/dgc/cdgc.git/commitdiff_plain/c8b9c37decb76b4667358e4d95ff928eb9f8fc8c

Adapt conservative default to the compiler support

When compiling the GC with a compiler that doesn't provide PointerMap
information, the conservative option defaults to true, as most likely the
GC will be used with programs compiled with the same compiler and all data
will be scanned conservatively anyway.
