Using GCC_EXEC_PREFIX

[Zhi-Wei Lu]

Hi gcc guru,

I have just finished compiling gcc 2.95.3 on a Redhat 7.1 system.
When I set 
export GCC_EXEC_PREFIX=/usr/i386-glibc21-linux/lib/gcc-lib/
(the redhat 6.2 glibc 2.1 compatible library) and try to compile anything, 
the compiler still use /usr/include instead of /usr/i386-glibc21-linux/include.

The stock redhat compiler gcc 2.96 works fine with the compatible libary.

How could I configure 2.95.3 so that it will work with the compatible library?

I notice that 

strings /usr/bin/gcc | grep GCC_EXEC_PREFIX gives (for gcc 2.96)
GCC_EXEC_PREFIX
GCC_EXEC_PREFIX=

the same command on my gcc 2.95.3 gives only
GCC_EXEC_PREFIX

Thanks for your help
