Hello,

I'm trying to solve small MICO build issue on Solaris/GCC platform. The issue is simple: since GCC 3.4.0 we start to fail compiling code which uses asinl and other functions. The actual issue is that configure (generated by autoconf2.13) detects asinl (and others) function as available, while in fact it is not available on the system (headers/libs), but it is available only in GCC's libstdc++ (as a symbol not as a function defined in header file). So this misdetection of asinl and others then cause MICO build to fail since asinl and others are not defined in header files.

I've studied this issue on linux and solaris with GCC 3.4.x and 4.0.1 and found that interestingly _GLIBCXX_HAVE_ASINL is defined when libstdc++ do not provide asinl symbol (function) and it is not defined when it provides it. I have two questions with regarding to this:

1) is this issue GCC's bug to publicly expose asinl/ldexpl/frexpl/fmodl/ceill/floorl/fabsl symbols in its libstdc++?

2) is it reliable to use _GLIBCXX_HAVE_ASINL to detect if asinl is just exposed by libstdc++ and not supported by the target OS?

Thanks,
Karel
