Hi. Thanks for your note.

I develop locally. My system is Ubuntu 16.04 with gcc 5.4 on a Skylake
Core i5. /proc/cpuinfo claims 4 CPUs, so there are likely two hyperthreaded
physical cores and there's plenty of RAM. The machine is quite fast,
even though it's using a conventional disk.


I often have to go through this cycle:


make distclean
./bootstrap.sh # set modification times on some files
./configure && make && make check


For example, when merging into the (too-many) different branches
and encountering a conflict.


The time difference between using tcc on the one hannd and GCC + make
-j on the other is quite noticeable; tcc + make -j is even faster.
Doing many builds an hour can happen, and a faster compiler saves me time.
tcc also makes a VERY noticeable difference in the time it takes
to run configure.


When I posted, tcc wasn't an option since it didn't check for duplicate
case labels, and PCC had stopped working for me. So I was seeking an
additional, fast compiler.


Dorking with the Makefile to only use -O on certain files isn't really
an option; autotools sets things up to compile everything the same way
and for the shipped tarball that is the right option.


Similarly, I don't really wish to switch off the autotools; I've too
much time and experience invested in them. They work, crufty as they are,
and I have not had to invest any real time in keeping things up to date
with respect to them.


Since I originally posted, someone suggested that I just fix tcc on
my own. I was able to do this with less than 2 hours work so now
I'm back to being fat, dumb and happy. :-)


Thanks,


Arnold
