Cygwin 1.7 string pattern matching problem with case sensitivity

[jean-benoit.ouellet@bell.ca]

Hi!
I just upgraded Cygwin from 1.5.21-2 to 1.7.8-1 and I'm getting problems with case sensitivity.
Let's assume that 'file.csv' contains these 2 lines:
Hello, 123
hello, 456 

The following commands will output both lines instead of the desired first line only:
awk -F, '$1 ~ /^[A-Z]/ {print $0}' file.csv
grep "^[A-Z]/" file.csv

There must be something wrong in my setup but I'm running out of ideas to find the problem rootcause.
