------- Comment #2 from davek at gcc dot gnu dot org 2007-04-25 01:23 ------- It determines the calling convention used, and is therefore surely the territory of the system headers/libs. Do take a look at the upstream source:
http://sourceware.org/cgi-bin/cvsweb.cgi/src/newlib/libc/include/_ansi.h?rev=1.4&content-type=text/x-cvsweb-markup&cvsroot=src after all, it comes from the same place mprec comes from. Someone snipped the #if __CYGWIN__ clause somewhere down the line. Would you be happier with a patch that just imported that block of definitions verbatim from newlib? I don't think it's likely to change often and need resyncing! -- http://gcc.gnu.org/bugzilla/show_bug.cgi?id=31662
