Description: make check fails in float4 and float8
Details:

Hallo,

while trying to install PostgreSQL 8.0.0 RC4 on different versions of SUSE
Linux, I had a Problem with SUSE Linux 7.0.

PostgreSQL-Version is 8.0.0 RC 4
Configure command: ./configure --prefix=/usr/wws/postgres --without-java
--without-tcl

uname -a: Linux lepserver2 2.2.16 #1 Wed Aug 2 20:22:26 GMT 2000 i686
unknown
gcc --version : 2.95.2
libc version : 2.1.3

Description: after configure and make a make check reports to failiures in
the float4 and float8 tests. A diff -u for these tests give the following
results:

Additional information:
A small test program showed that the implementation of strtod in this
version of glibc is quite "special": 'inf' is understood but 'infinity' is
not.
after a call to
strtod("infinity",&end)
*end points to "inity", and not to the end of the input as expected.
