[help-cgicc] a note about building cgi-3.2.2 under RH7.3 (and gcc 2.96)

[g.p.ciceri]

Hello all,
I've tried to build cgicc under Redhat 7.3
(with the old compiler gcc 2.96).

I take the following error
---
 g++ -DHAVE_CONFIG_H -I. -I. -I. -I.. -I.. -Wall -W -pedantic -g -O2 
-MT CgiEnvironment.lo -MD -MP -MF .deps/CgiEnvironment.Tpo -c 
CgiEnvironment.cpp  -fPIC -DPIC -o .libs/CgiEnvironment.o
CgiEnvironment.cpp: In method `void cgicc::CgiEnvironment::parseCookie
(const string &)':
CgiEnvironment.cpp:141: parse error before `__ctype_b'
CgiEnvironment.cpp:141: parse error before `]'
CgiEnvironment.cpp:149: confused by earlier errors, bailing out
make[2]: *** [CgiEnvironment.lo] Error 1

---

Googling here and there, I've found a note:
http://gcc.gnu.org/onlinedocs/libstdc++/17_intro/porting-howto.html
stating issues for Libc-macros and old implementations of libstdc++
(like the one in g++ 2.96). One proposed solution was not to use
<cctype> and std:: namespace but revert to the C <ctype.h>.

So I've switched for gcc 2.x to the C
behaviour with some #if... #endif in two places.

First, to select the right include
(CgiEnvironment.cpp, about row 26)
---
#if (__GNUG__ == 2)
    // for old g++ v2.96, we use ctype.h
#   include <ctype.h>
#else
#   include <cctype>
#endif
---

Second, to choose the right isspace call
(CgiEnvironment.cpp, about row 141)
---
#if (__GNUG__ == 2)
   // for old g++ v2.96, we use ctype.h
   if(isspace(*data_iter) == 0)
#else
   if(sdt::isspace(*data_iter) == 0)
#endif
---

Now all seems to build well. Demos run.
I've not tested back on gcc 3.x, however.

Any remark will be appreciated.

HTH
