recog.c:2104

Severity: normal
Priority: P3

Sorry if this was previously reported. Searching returned an error stating I
used an invalid file extension.
I was attempting to compile the latest Crypto++ (svn checkout
https://cryptopp.svn.sourceforge.net/svnroot/cryptopp/trunk/c5 cryptopp) on a
Dell GX280 (32 bit Pentium 4). Here's the internal compiler error:
$ export PREFIX=/usr/local; make
g++ -DNDEBUG -g -O2 -m32 -mtune=pentium4 -march=native -pipe -c 3way.cpp
g++ -DNDEBUG -g -O2 -m32 -mtune=pentium4 -march=native -pipe -c adler32.cpp
g++ -DNDEBUG -g -O2 -m32 -mtune=pentium4 -march=native -pipe -c algebra.cpp
g++ -DNDEBUG -g -O2 -m32 -mtune=pentium4 -march=native -pipe -c algparam.cpp
g++ -DNDEBUG -g -O2 -m32 -mtune=pentium4 -march=native -pipe -c arc4.cpp
g++ -DNDEBUG -g -O2 -m32 -mtune=pentium4 -march=native -pipe -c asn.cpp

Please submit a full bug report,
with preprocessed source if appropriate.
See <file:///usr/share/doc/gcc-4.5/README.Bugs> for instructions.
make: *** [asn.o] Error 1
===================================================================
Additional information
I modified Crypto++'s GNUMakefile a bit:
OLD:
CXXFLAGS = -DNDEBUG -g O2
MOD:
CXXFLAGS = -DNDEBUG -g -O2 -m32 -mtune=pentium4
When I invoked `make` I used the following:
$ export PREFIX=/usr/local; make
$ g++ --version
g++ (Ubuntu/Linaro 4.5.2-8ubuntu4) 4.5.2
