@ -34,9 +34,24 @@ Some of the single letter option names refer to an option being off,
in which case the inversion of that name refers to the option being on.
For example, `tt(PLUS()n)' is the short name of `tt(exec)', and
`tt(-n)' is the short name of its inversion, `tt(noexec)'.
In strings of single letter options supplied to the shell at startup,
trailing whitespace will be ignored; for example the string `tt(-f )'
will be treated just as `tt(-f)', but the string `tt(-f i)' is an error.
This is because many systems which implement the `tt(#!)' mechanism for
calling scripts do not strip trailing whitespace.

FreeBSD: FreeBSD 2.2.7 [3.1.4]

apparently needs configuring with explicit flags when compiling
with debugging enabled:
DLLD=gcc LDFLAGS='-g -rpath <path-to-.so-files>' ./configure ...
FreeBSD: FreeBSD 2.2.7, 3.x, 4.x

HP: HP-UX 9, 10.20
Problems with dynamic loading have been reported under 11, but
this should compile using the standard dlopen() function set
(rather than the 10.20 shl_load() function set). More details of
any difficulties would be appreciated.
IBM: AIX 3.2, 4.1
Should build `out-of-the-box', but --enable-zsh-mem will not work.
On 3.2, for 64-bit integer support you need to compile with gcc, as
the native compiler does not support ANSI simulataneously with
`long long'. On 4.1, there appear to be problems using
--enable-dynamic (the default) with gcc (version was 2.7.2.3) in
4.1, though native cc works. More information about this problem
would be appreciated.

Linux: Linux (i386) [3.1.4]
If you are using an early minor version of libc 5, then a bug
in the auto-configuration process may cause zsh to think that
your system doesn't support the lstat function. If the configure
process reports that there is no lstat, edit config.h and change
HAVE_LSTAT to 1. libc-5.2.18 or later does not have this problem.
Various problems have been reported when using optimisation
with the experimental GNU compiler, egcs. In particular,
on Linux Alpha with egcs 1.0.3a and 1.1.1 using -O1 or greater,
the completion code is not correctly compiled.
Some versions of glibc2 have a conflict with <asm/resource.h>
which causes a redefinition warning on RLIM_INFINITY. This
causes configure to decide that <sys/resource.h> is not present,
which can cause compilation errors in zsh's rlimit code. The
best solution is to edit config.h after running configure and
#define HAS_SYS_RESOURCE_H.
