or as MAXPATHLEN, _MAX_PATH, or MAX_PATH if either of them is available, or as 1024 if none are available. this would make us safer in deep installation directory paths. darkplaces engine seems to do the same. git-svn-id: svn://svn.code.sf.net/p/quakespasm/code/trunk/quakespasm@928 af15c1b1-3010-417e-b628-4374ebc0bcbd

/* NOTES on TYPE SIZES:
|
|
Quake/Hexen II engine relied on 32 bit int type size
|
|
with ILP32 (not LP32) model in mind. We now support
|
|
LP64 and LLP64, too. We expect:
|
|
sizeof (char) == 1
|
|
sizeof (short) == 2
|
|
sizeof (int) == 4
|
|
sizeof (float) == 4
|
|
sizeof (long) == 4 / 8
|
|
sizeof (pointer *) == 4 / 8
|
|
For this, we need stdint.h (or inttypes.h)
|
|
FIXME: On some platforms, only inttypes.h is available.
|
|
FIXME: Properly replace certain short and int usage
|
|
with int16_t and int32_t.
