[PATCH] Several libc functions detection

[Mads Martin Joergensen]

Hey together,

I was a little disturbed by the following snippet from the configure
output:

[...]
checking for sigaction... yes
checking for strftime... no
checking for strcasestr... yes
checking for snprintf... no
checking for vsnprintf... no
checking for catopen... yes
[...]

Since I for sure have these 3 functions on my system.

I looked into it, and found out it depends on where the tests are
performed. When done before AC_LANG(C++) they all succeed, and they
are not libstdc++ functions, so please apply the following patch:

If you wonder why it might work on your systems the reason most probably
is I use gcc-3.3-pre here.
