Subject: utils/macros.h: Refactor the GCC-ish compiler support.
X-Git-Tag: 2.2.4~10
X-Git-Url: https://git.distorted.org.uk/~mdw/mLib/commitdiff_plain/d94956b547ca1a477e8b464c58516aca3cccccb9?hp=d94956b547ca1a477e8b464c58516aca3cccccb9

utils/macros.h: Refactor the GCC-ish compiler support.

Fully define `GCC_VERSION_P' early, and then use it without any other
guard to define the GCC-specific hacks.  This way, it's easy to support
other compilers which behave similarly, by defining an appropriate
`FOO_VERSION_P' macro, and then adding appropriate extra alternatives to
the individual guards.

No functional changes.
