[New-bugs-announce] [issue29243] --enable-optimizations makes common build commands always need to compile from scratch

[Xiang Zhang]

New submission from Xiang Zhang:

In 3.6 we get --enable-optimizations. One thing I find annoyed with this flag is that it makes some build commands compile from scratch since it always clears the environment first. For example, with the commands listed at the top of Makefile:

./configure
make 
make test
make install

It compiles 3 times and considering the optimized build needs more time every time, it lasts long.

I am not sure this is a problem and feel free to close it.
