Thank you Elena, I had a doubt that this is because of mixing up of compiler libraries. I found that somehow LDFLAGS and CPPFLAGS were not set in the *Makefile*, even though I set them as mentioned in the INSTALL readme file:
LDFLAGS=-L<GCCLIB> CPPFLAGS=-I<GCCINCLUDE> So I added LDFLAGS and CPPFLAGS in the Makefile post configure and HDF5 is compiling with both versions of gcc. Thanks again.
