some question about ANSI C

["Rolland Wong" <rolland@linkmark-tech.com>]

Dear Sir/ Madam,
 
    I'm not sure if I wrote to a right 
party..   
    I've encounter a problem while compile the 
program, mod_perl.
    I can successfully compile the mod_ssl and 
Apache v1.3.9 without any problem.
    But when I try to compile the mod_perl 
v1.21 into Apache Source in order to include this program, the makefile seems 
not really like the GCC v2.95.2. It got the following error message 
:-
 
Configure mod_perl with ../apache_1.3.9/src ? [y] Shall I 
build httpd in ../apache_1.3.9/src for you? [y] Appending mod_perl to 
src/Configuration Using config file: 
/source/javaserver/mod_perl-1.21/src/Configuration Creating 
Makefile  + configured for Linux platform  + setting C compiler 
to gcc  + setting C pre-processor to gcc -E  + checking for 
system header files  + adding selected modules  + checking 
sizeof various data types  + doing sanity check on compiler and 
options ** A test compilation with your Makefile configuration ** failed. 
This is most likely because your C compiler ** is not ANSI. Apache requires 
an ANSI C Compiler, such ** as gcc. The above error message from your 
compiler ** will also provide a clue.
    It's great the if you can help me to solve 
this problem, since I've asked Apache while they said this problem should 
related to GCC and not them...
 
    Thanks again for your patient and awaiting 
for your reply.
 
Best Regards,
