On cygwin, gfortran -fopenmp gives the warning
gfortran: unrecognized option '-pthread'
which gives a heap of failures in the testsuite.
This is set in gcc.c:
/* Adding -fopenmp should imply pthreads. This is particularly important
for targets that use different start files and suchlike. */
#ifndef GOMP_SELF_SPECS
#define GOMP_SELF_SPECS "%{fopenmp: -pthread}"
#endif
I think the fix is to override it, as is done in gcc/config/darwin.h
/* Every program on darwin links against libSystem which contains the pthread
routines, so there's no need to explicitly call out when doing threaded
work. */
#undef GOMP_SELF_SPECS
#define GOMP_SELF_SPECS ""
I'll prepare a patch at some stage.
