Compiling GFortran - mpfr_

[Daniel Carrera]

Hello,

I'm having trouble compiling a clean copy of GFortran. I'm getting 
linker errors about "mpfr_" functions. For example:

/usr/bin/ld: libbackend.a(builtins.o): in function 
fold_builtin_1:builtins.c(.text+0x11dd9): error: undefined reference to 
'mpfr_asinh'
/usr/bin/ld: libbackend.a(builtins.o): in function 
fold_builtin_1:builtins.c(.text+0x11e1d): error: undefined reference to 
'mpfr_asin'
/usr/bin/ld: libbackend.a(builtins.o): in function 
fold_builtin_1:builtins.c(.text+0x11e61): error: undefined reference to 
'mpfr_acosh'
/usr/bin/ld: libbackend.a(builtins.o): in function 
fold_builtin_1:builtins.c(.text+0x11ea5): error: undefined reference to 
'mpfr_acos'


I am under the vague impression that this has something to do with the 
quad precision library, but I don't really understand what the problem 
is or how to fix it. Help?

Cheers,
Daniel.
