[krbdev.mit.edu #7895] problem compiling krb5-appl 1.0.3 with GCC 4.6.3 on Gentoo Linux

[Vanush Misha Paturyan via RT]

Hi all,

krb5-appl-1.0.3 failed to compile on my Gentoo Linux system running
GCC 4.6.3 and GLibc 2.17.
Compilation fails with:

In file included from /usr/include/sys/param.h:28:0,
                 from ftp_var.h:115,
                 from cmdtab.c:41:
/usr/include/signal.h:217:24: error: redefinition of typedef ‘my_sig_t’ with different type
ftp_var.h:62:19: note: previous declaration of ‘my_sig_t’ was here

This looks very similar to the bug reported here (#3243):
http://kerberos.996246.n3.nabble.com/krbdev-mit-edu-3243-compilation-problem-under-FreeBSD-4-11-RELEASE-tt318.html

Fix proposed by #3243 (see below) allows compilation to finish, but I haven't
checked if the produced binary works as expected.
