- Subject: [OBV] Fix arm-tdep.c compilation for cygwin gcc 3.4.4
Cygwin GCC 3.4.4 (legacy 1.5 version)
chokes on arm-tdep.c compilation
about the use of a possibly unset local
variable found_stack_adjust.
Examining the source, I found that this warning
is correct, despite the fact that it apparently
does not show up for later versions of gcc,
like gcc 4.3.4 of the Cygwin 1.7 version.
I committed the following patch
under the obvious rule, after testing
on GCC compile farm x86_64-unknown-linux-gnu machine.

* arm-tdep.c (arm_in_function_epilogue_p): Fix code to avoid
possible used of uninitialized variable.
