Subject: Fix & make linux conditionals uniform (#4278)
X-Git-Tag: 0.4.15~336
X-Git-Url: https://git.librecmc.org/?a=commitdiff_plain;h=1dfd977ec43370da6931b11a8d0469792c8ebc36;p=oweals%2Fminetest.git

Fix & make linux conditionals uniform (#4278)

The source used a hodge-podge of different combinations of different
macros to check for linux: 'linux', '__linux', '__linux__'.

As '__linux__' is standard (Posix), and the others are not, the source
now uniformly uses __linux__. If either linux or __linux are defined,
it is made sure that __linux__ is defined as well.
