            Bug ID: 100598
           Summary: MinGW Canadian cross toolchain fails to build due to
                    missing BASEVER in genversion.c
           Product: gcc
           Version: 12.0
            Status: UNCONFIRMED
          Severity: normal
          Priority: P3
         Component: other
          Assignee: unassigned at gcc dot gnu.org
          Reporter: markus.boeck02 at gmail dot com
  Target Milestone: ---

I am currently unable to build trunk version of gcc due to a compiler error
when compiling the file genversion.c. This happens when crosscompiling a GCC
toolchain for a x86_64-w64-mingw32 host.

The compiler error:
../../gcc/genversion.c: In function ‘int main()’:
../../gcc/genversion.c:37:20: error: ‘BASEVER’ was not declared in this scope
   char basever[] = BASEVER;
                    ^~~~~~~
../../gcc/genversion.c:50:11: error: ‘DEVPHASE’ was not declared in this scope
   phase = DEVPHASE[0];
           ^~~~~~~~
../../gcc/genversion.c:73:39: error: expected ‘)’ before ‘BASEVER’
   printf ("#define version_string \"" BASEVER DATESTAMP DEVPHASE REVISION
"\"\n");
                                       ^~~~~~~
../../gcc/genversion.c:74:42: error: expected ‘)’ before ‘PKGVERSION’
   printf ("#define pkgversion_string \"" PKGVERSION "\"\n\n");
                                          ^~~~~~~~~~
../../gcc/genversion.c:82:39: error: expected ‘)’ before ‘BUGURL’
   printf ("#define bug_report_url \"" BUGURL "\"\n\n");
                                       ^~~~~~
make[2]: *** [build/genversion.o] Error 1
make[2]: *** Waiting for unfinished jobs....


The compile command used in the build is:
g++ -c -DIN_GCC      -DGENERATOR_FILE  -I. -Ibuild -I../../gcc
-I../../gcc/build -I../../gcc/../include  -I../../gcc/../libcpp/include
-I/mnt/c/GCC-Build/NewestLinux/Libraries/include \
        -o build/genversion.o ../../gcc/genversion.c

where g++ is 7.5.0 shipped with Ubuntu 18.04 which I am using as build
environment. 

The configure command used is:
