Tue Jul 13 23:37:18 1999 Andrew Cagney <cagney@b1.cygnus.com>
* gdb.base/configure.in: Check for gdbvars.exp instead of
a1-selftest.exp.
* gdb.base/configure: Re-generate.
1999-07-12 Stan Shebs <shebs@andros.cygnus.com>
* gdb.base/selftest.exp: Rename from a1-selftest.exp, no point
in trying to run first and name is too long.
* gdb.base/pointers.c, gdb.base/pointers.exp: Add contents of
pointers2.c and pointers2.exp, respectively.
* gdb.base/pointers2.c, gdb.base/pointers2.exp: Remove, makes
doschk happier.
1999-07-08 Stan Shebs <shebs@andros.cygnus.com>
* gdb.base/callfwmall.c, gdb.base/callfwmall.exp: Renamed from
