Identifying system with macro

[Andrea D'A. <and...@gm...>]

Hello,
in 4.4.2 src/variable.c:247 the _Macintosh macro is checked to see if
the system is a Mac but who's supposed to set such a macro? It's not
one of gcc's predefined macro on OS X (not since a few major versions
at least).

The current resulting default fontpath is
/usr/X11R6/lib/X11/fonts/Type1 that isn't even present on a standard
10.6 system.
I've changed _Macintosh to __APPLE__ in order to have a consistent
default fontpath value [1]

Btw why do a few paths in variable.c have a trailing exclamation mark
while others don't?


Regards
