What is g++-3 / gcc-3?

Trying to use make from cygwin using g++ I was getting Access Denied error messages. Googling the error message I found a positing referring to g++-3 and gcc-3 http://www.linuxquestions.org/questions/linux-software-2/cygwin-g-3开发者_如何学C-exe-gcc-3-exe-corrupted-to-g-3-exe-dam-and-gcc-3-exe-dam-769722/)...

Changing the compiler to g++-3 seems to fix the problem although I cannot find much information about both g++-3 and gcc-3.

Any ideas where I can find more information about them>

To answer your point in the comment to Pete's answer, the gcc you type on the terminal is just a symlink to the actual gcc binary. It makes it easy to upgrade since you can just point the symlink to something else.

$ which gcc
/usr/bin/gcc
$ ll /usr/bin/gcc
lrwxrwxrwx 1 root root 7 2010-09-01 11:10 /usr/bin/gcc -> gcc-4.4*

I'm guessing it's version 3 of g++. just like g++-4.1.2 would be version 4.1.2
