There is no /usr/lib/gcc/x86_64-linux-gnu/9/include-fixed directory.

This could actually be a bug in libgcc-9-dev, as libgcc-8-dev
provides "/usr/lib/gcc/x86_64-linux-gnu/8/include-fixed/limits.h".

Bug#953806: cpp-9: no include path in which to search for limits.h

[Vincent Lefevre]

Package: cpp-9
Version: 9.3.0-1
Severity: grave
Justification: renders package unusable

The compilation of a simple program like

#include 

int main (void)
{
  return 0;
}

now fails:

cventin:~> gcc-9 tst.c -o tst
In file included from tst.c:1:
/usr/include/limits.h:124:26: error: no include path in which to search for 
limits.h
  124 | # include_next 
  |  ^

or directly with "cpp-9 tst.c".

Since this issue does not occur with other GCC versions, I suppose
that this is a bug in cpp-9, not in libc6-dev.
