On Cygwin, with gdc, I see this warning message:
Warning: implementation flavor of 'x86_64-pc-cygwin-gdc' not recognized.
This patch fixes it.
2025-04-01 Bruno Haible <br...@clisp.org>
dcomp-script: Handle gdc binaries named <host>-gdc.
* m4/dcomp.m4 (gt_DCOMP): Look only at the first word of the --version
output and accept a "<host>-" prefix.
* build-aux/dcomp.sh.in: Likewise.
