[cfe-dev] Another Linker error with clang++

[Devchandra L Meetei]

Downloaded the latest  code base from svn and did make -ENABLED_OPTIMISED=1
The resultant binary compiles and linked perfectly
However,
very preliminary comparison results with time command
-------------------
clang++
real    5m44.626s
user    4m54.984s
sys     0m42.463s
----------------------
g++
real    5m16.298s
user    4m10.836s
sys     0m47.825s

The resultant binaries of my project with clang is 319 MB and whereas g++
one is 302 MB
