Initial Comment:
PROBLEM:
========

If I use the following code:

lv_rcode = regcomp(&lr_re, ms_RegExp, 
REG_EXTENDED);

lv_rcode = regexec(&lr_re, &lv_string[0], 1, &pm, 0);

to find the following text: 

cm582172

Using the following regular expression

[A-Z]{2}[[:space:]]*[0-9]{6}[[:space:]]*

The text if found.

However if I use instead the following code

boost::regex regx(config.vRegx.at(iCnt).c_str());
flags = boost::match_default;
boost::regex_search(start, end, what, regx, flags)

With the same regular expression it does not find the 
string unless I use the following regular expression:

[a-z]{2}[[:space:]]*[0-9]{6}[[:space:]]*

The difference is the lower case of the alpha range [a-z]

My question:

Is there a way I can use regexec to be case sensitive for 
the alpha range like it is with regex_search function?

Thanks,

Matias
