            Bug ID: 30882
           Summary: MinGW: undefined reference to `getline' in
                    m32c/opc2c.c
           Product: gdb
           Version: 13.1
            Status: UNCONFIRMED
          Severity: normal
          Priority: P2
         Component: build
          Assignee: unassigned at sourceware dot org
          Reporter: orgads at gmail dot com
  Target Milestone: ---

When building with gdb on MinGW64 with simulators enabled, I get the following
warning:

../../gdb-13.2/sim/m32c/opc2c.c: In function 'main':
../../gdb-13.2/sim/m32c/opc2c.c:541:10: warning: implicit declaration of
function 'getline' [-Wimplicit-function-declaration]
  541 |   while (getline (&linebuf, &len, in) >= 0)
      |          ^~~~~~~

And it fails to link:

ld.exe: m32c/opc2c.o:opc2c.c:(.text.startup+0x123): undefined reference to
`getline'
collect2.exe: error: ld returned 1 exit status
make[1]: *** [Makefile:3343: m32c/opc2c.exe] Error 1

the top-level configurey already supports building subdirs for the --build
system.  so i posted some patches to leverage that and link them in to our
build-time tools.

As of 14.1, this is still broken.
