Real men write their configure checks by hand, although whether the rrdtool
maintainer is a male is not clear so far. ;-)

Though I don't know the why, rrdtool-1.2.10/configure.ac has the
following macro.

I'm writing a gcc back-end for a new RISC.
This RISC has two kinds of add instructions,
one updates condition register and one doesn't.
ex.
1.)
add <- add
comp<- update condition register
2.)
add_c <- add & update condition register
But case 2 pattern is not used at al

It's caused by -frename-registers enabled by -funroll-loops. Compiling
with -O2 -fno-unroll-loops -fprofile-generate compared to -O2 -

Can someone explain why libgnat is defaulted to STATIC? I would think that
SHARED would be the desired default.
Does SHARED cause problems when building cross compilers?

Please update http://gcc.gnu.org/java/index.html and mention
how much of the Java 1.5 spec that GCJ currently implements.
When I refer folks to GCJ, the first thing they usually ask is,
"does it support generics?" "autoboxing?" and so on. That info
should be right up on the GCJ front page -- even

This past week I have been looking into type mismatch in simple cases
in GCC.
These simple cases include non compatible types on the two sides of the
MODIFY_EXPR
and comparisons. All the bugs I have found so far have been filed.
They are all listed
under the meta-bug, PR 22368.
