Problem to rebuild Xalan 1.4 with ICU 2.2

[mv...@amadeus.net]

Hello,

I need to rebuild Xalan with ICU, as I need to use the format-number() 
function.

I have downloaded ICU (ver. 2.2) and tried to build it on the HP-UX 
platform. As my "cc" is not an ANSI-C compiler...

gmake[1]: Entering directory `/homedev/mvasice/ICU/icu/source/common'
cc -DHAVE_CONFIG_H -DU_COMMON_IMPLEMENTATION  -I. -I.  -O -O2  +Olibcalls 
-Ae +ESlit -c  +z -o putil.o putil.c
(Bundled) cc: warning 480: The -O option is available only with the C/ANSI 
C product; ignored.
(Bundled) cc: warning 480: The -O option is available only with the C/ANSI 
C product; ignored.

...I have dowloaded gcc and tried to use it as an ANSI-C compiler. But I 
do not succeed to compile a single source file. Almost all options are not 
recognized by gcc and "-o" and "-c" can't be specified together.

Here are the specs:

aCC:            HP ANSI C++ B3910B A.03.30
gmake:          GNU Make version 3.79.1, built for hppa2.0w-hp-hpux11.00
gcc:            version 3.2, built for hppa2.0n-hp-hpux11.00


ICU Readme file doesn't provide too many details on building the ICU. Any 
help is more than welcome!

Cheers, Miro.
