[syslinux] [patch] ./configure problem on Solaris

[Mike Bristow]

Hi,

I have a problem with tftpd-hpa on Solaris-8, in that the configure
script cannot find the regex engine.

This is because of the following in configure.in:

LIBXTRA=false
AC_SEARCH_LIBS(xmalloc, iberty, , LIBXTRA=true AC_LIBOBJ(xmalloc))
AC_SEARCH_LIBS(xstrdup, iberty, , LIBXTRA=true AC_LIBOBJ(xstrdup))
AC_SEARCH_LIBS(bsd_signal, bsd, , LIBXTRA=true AC_LIBOBJ(bsdsignal))
if $LIBXTRA; then
        LIBS="../lib/libxtra.a $LIBS"
fi

Solaris doesn't have xmalloc and friends available and so LIBS
includes ../lib/libxtra.a.

This causes all future invokations of the compiler to fail like so:

configure:10955: /opt/SUNWspro/bin/cc -o conftest  -fast -g -xs -v -xstrconst -xdepend         -xtarget=ultra2 -xarch=v8plusa -xprefetch -fast -g -xs -v -xstrconst -xdepend         -xtarget=ultra2 -xarch=v8plusa -xprefetch -D_XPG4_2 -D_XOPEN_SOURCE -D__EXTENSIONS__ -D_BSD_SOURCE -D_ISO9X_SOURCE -D_OSF_SOURCE -D_XOPEN_SOURCE_EXTENDED -fno-strict-aliasing   -xildoff -xildoff -xildoff -xildoff conftest.c ../lib/libxtra.a -lresolv -lnsl -lsocket  >&5
cc: Warning: illegal option -fno-strict-aliasing
ld: fatal: file ../lib/libxtra.a: open failed: No such file or directory
ld: fatal: File processing errors. No output written to conftest

Because, of course, libxtra doesn't exist yet.  

(The illegal option warning is annoying in the build logs, but
harmless and easily ignorable).

I've attached a patch which I believe fixes this problem, without
any undesirable side effects.

Can anyone see a problem with it?

Ta,
Mike
