Of course not! (:-)) I just pointed out that some functions have one
external name under Win32 and another under Linux. They "wisely" used
#define to achieve this fantastic effect. I don't even asked them to fix
the mess, only to add an alias name to either distribution. The answer was
"won't do it".

Having said that, I used Glib in order to do things the Ada standard
library does wrong. Its directories (devices, file system) and OS calls
packages are designed OS-dependent, which is unacceptable. Glib by all its
drawbacks at least tries to make this right.
