Pavel M <pavel.morozkin at gmail dot com> changed: What |Removed |Added ---------------------------------------------------------------------------- CC| |pavel.morozkin at gmail dot com --- Comment #12 from Pavel M <pavel.morozkin at gmail dot com> --- As far as I understand, support of #pragma STDC xxx is required by the C standard for hosted implementation. If so, then it is worth reaching conformance to increase the priority of this issue. It is logical for the end users to expect the support of #pragma STDC xxx. Now they see: t888.c:3: warning: ignoring ‘#pragma STDC FP_CONTRACT’ [-Wunknown-pragmas] t888.c:4: warning: ignoring ‘#pragma STDC FENV_ACCESS’ [-Wunknown-pragmas] t888.c:5: warning: ignoring ‘#pragma STDC CX_LIMITED_RANGE’ [-Wunknown-pragmas] Invoked with: gcc t888.c -c -std=c11 -Wall.
