Installing GNU Compiler 51
If you want to enable threads on Linux systems, you can use --enablethreads=posix
as a command line option.
3.2.2.3 Building GCC
It is recommended that you use GNU make for building purpose. Running the make
bootstrap command will build the compiler, libraries and related utilities. Following is part
of the output when you start the building process.
[root@laptop objdir]# make bootstrap
make[1]: Entering directory `/gcc3/objdir/libiberty'
if [ x"" != x ] && [ ! -d pic ]; then \
mkdir pic; \
else true; fi
touch stamp-picdir
if [ x"" != x ]; then \
gcc -c -DHAVE_CONFIG_H -g -O2 -I. -I../../gcc-3.0.4/

else true; fi

Again most of the output is truncated. The building process may take a long time depending
upon how powerful a computer you are using for building GCC. The process is completed in
