question about cproj, cprojf

[Yuki Kimoto]

Hi, I'm Yuki Kimoto

I have one problem.

I'm SPVM programing language author. This is C transpiler from Perl syntax.

https://github.com/yuki-kimoto/SPVM

gcc is used to compile C language produced by SPVM library

Old glibc cproj, cprojf is different from new implementation of cproj,
cprojf.

I provide new cproj, cprojf on SPVM in old glibc.

If I can know, I want to know the version check way and see cproj
implementation.
