bowtie 2 on win7 bits32 installation?

[Triple_W]

When i install bowtie 2 by Cygwin (on win7 32 bits), the problem occured in the following:



/usr/bin/g++ -O3 -m32 -msse2 -funroll-loops -g3 -DCOMPILER_OPTIONS="\"-O3 -m32 -msse2 -funroll-loops -g3 \"" \
-fno-strict-aliasing -DBOWTIE2_VERSION="\"`cat VERSION`\"" -DBUILD_HOST="\"`hostname`\"" -DBUILD_TIME="\"`date`\"" -DCOMPILER_VERSION="\"`/usr/bin/g++ -v 2>&1 | tail -1`\"" -D_LARGEFILE_SOURCE -D_FILE_OFFSET_BITS=64 -D_GNU_SOURCE -DBOWTIE_PTHREADS -DPREFETCH_LOCALITY=2 -DBOWTIE2 -DNDEBUG -Wall \
