I have a perl xs module that, up until recently, has been built on linking to a vendor's static libraries (.a) using gcc. The machine that I build it on is a Sun box.

However, they have recently started shipping only the dynamic libraries (.so). I've fixed my Makefile.PL to use these new libraries and built it all again.

The LIBS entry changed from 
'LIBS'      => ["-L$DIR/acelib -lace -lz4t -lffstub -L$DIR/comlib -ldi
+racc -lmas -lliud -llgen -loptec -lm -lpsthr"],

[download]
to... 
'LIBS'      => ["-L$DIR -lace"], # libace.so

[download]

All seems to work great. However, the vendor documentation comes with a statement saying that they built their software using the "Sun One version 8" compiler and that I should be using it too. (It says they used gcc for Linux builds) It also says...

"Before using ACE 7.50c, you must ensure that your C++ Standard Library (runtime version) is compatible with the new compilers." (for me this would be the Sun One v8)

and...

"Verify that your system administrator has obtained an appropriate C++ runtime version of the appropriate compiler from your operating system vendor..."

Why would it matter what compiler I use?
